i'm glad you're here. let me tell you, you could not have picked a better night to join us. we have some major star power under this roof tonight. johnny depp is with us tonight. [ cheers and applause ] linkin park is with us tonight. [ cheers and applause ] sitting in with the cletones, rock 'n' roll hall of famer, the great ann wilson from heart is here. [ cheers and applause ] if that isn't enough, the reason all the ladies have been lined up since last night, camping out in tents, "science bob" pflugfelder is with us. [ cheers and applause ] science bob always has something fun up his sleeve. most of the fun involves explosions. so tonight for the show, he built a huge -- two huge cannons, i think, from which to shoot a lot of ping-pong balls. for safety reasons we had to test it. here's how tt ent in rehearsal this afternoon. >> and three, two, one -- well, i'm fine, i think we might need to repair this, though. >> jimmy: that's not a cartoon character, that's a man. that's a human man. [ laughter [ laughter ] [ cheers and applause ] -- one heck of a week. the justice department appointed a special counsel to investigate ties between his campaign and russia which he did not like at all. but sources inside the white house say when he found out about it, he didn't yell or scream. he told his staff, brought them in, he said, we have nothing to hide. he was calm, he punched sean spicer in the stomach a few times. [ laughter ] just released the statement. so that's progress. but then this morning at 7:52 a.m., he got on twitter and wrote, this is the single greatest witch hunt of a politician in american history. even his witch hunts are the greatest in american history. [ laughter ] he also posted this. he posted, with all of the illegal acts that took place in the clinton campaign and obama administration, there was never a special counsel appointed. i'm not sure if he's bragging about that? [ laughter ] maybe that's because neither one of them fired the person who was investigating them at the time? [ laughter ] anyway, with all the drama going on trump is getting out of town, he's headed to saudi arabia tomorrow. he's going to give, this is not a joke, he's there to give a speech on islam. [ laughter ] seems like a good idea. i'm sure the muslim community is very eager to hear the -- [ laughter ] -- orange man who's trying to ban them from the country give a little speech. islam is fantastic, i have so many muslim friends. [ laughter ] trump will be out of the country for nine days. see, this is when they should put that travel ban in place. you know? [ laughter ] [ cheers and applause ] the president got practice for his trip overseas by holding a joint press conference with the president of colombia at which he was asked a dumb but straightforward question. >> as you look back over the past six months or year, have you had any recollection where you've wondered if anything you have done has been something that might be worthy of criminal charges in these investigations or impeachment as some on the left are implying? >> i think it's totally ridiculous. everybody thinks so. there was no collusion. and everybody, even my enemies, have said there is no collusion. >> jimmy: really? [ laughter ] which enemy said that? was it the riddler or the joker that said that? [ laughter ] according to multiple reports, there may be some changes when the president gets back from his trip. white house stress secretary sean spicer might not do his -- might not be allowed to do the daily press briefings anymore, which would be a shame because that's one of my favorite shows right now. sometimes i like to think what goes through sean spicer's head when he learns about the latest crazy thing his boss is up to. today reuters reported the trump campaign had at least 18 undisclosed contacts with the russians and this is how i imagine that went over. >> here's your paper, mr. spicer. >> [ bleep ]. [ laughter ] [ cheers and applause ] >> jimmy: understandably under a lot of pressure. the president made an interesting move today. he hosted a lunch at the white house with all the cable and network news anchors. he invited them all to the white house. he definitely spit in their food, though, right? [ laughter ] the lunch was off the record. which means by tomorrow we'll know every word of what was said. but on cnn today wolf blitzer did say the president was mad at the luncheon. it was supposed to be private but we obtained video which we can share with you now exclusively. this is video from inside the news anchor lunch at the white house today. ♪ [ laughter ] >> i've given you meats, wine, music. but i haven't shown you the hospitality you deserve. ♪ ♪ >> jimmy: oh, wow. [ cheers and applause ] only tucker carlson survived. tune in next season to see how it all turned out. here's some washington news that doesn't involve donald trump. this is from last night's game between the nationals and pittsburgh pirates. watch the kid at the end here. this is quite a moment. >> sunday is kids' day at pnc park. all kids 14 and younger taking home a pirates baseball glove. thanks to highmark and the pirates.com/kidsdays and get your tickets. always fun. [ laughter ] >> jimmy: don't worry, it's a light beer. i hope he's not driving them home. another good one. we have a team of tv watchers who spend all day and night looking for weird stuff. this is from last night's rangers game. you know you see people jumping around and popping up behind the local news reporter? tonight i'm proud to present what i believe might be at least from a fame standpoint, the single greatest behind the news moment of all-time. >> for more on mike napoli, we send it down to emily jones. >> yeah, i talked to nap about what's been the difference, what clicks for him. [ cheers and applause ] >> jimmy: she got photo bombed by president bush. he and obama are having a lot of fun with this i'll tell you. [ laughter ] i would like to offer congratulations to jay-z and beyonce. according to "forbes" magazine their combined net worth is now more than $1 billion. $1.16 billion. i think that should take care of all 99 of jay-z's problems. [ laughter ] they have twins on the way which means they're going to have to buy two car seats. and they probably have more than one car. so this is very good news, congratulations to them. [ laughter ] meanwhile a new season of "the bachelorette" begins on monday. abc, our network, i'm glad you're excited, has unveiled photographs of the 31 men who will vie for bachelorette rachel's love. chris harrison said rachel knows what she wants, she's not looking to date, she's looking for someone serious. oh boy did she come to the wrong place. [ laughter ] every season with a lot of help from my wife, i make a pick for who will go the distance on "the bachelor." i'll do that monday night when rachel is here, she'll be here monday. before i predict who will win, i want to take a moment to sing out to a few guys who based on photos alone i know they definitely won't. okay? number one is lucas. lucas lists his occupation as whaboom, which means i hate him already. so will rachel. lucas is out. next up, blake e., an aspiring drummer. [ laughter ] good-bye. blake, the "e" stands for "eliminated." [ laughter ] this next guy is jedediah. believe it or not he's an e.r. physician from georgia. which is great. but i just, sorry, don't see a jedediah winning this thing. [ laughter ] finally, we have jonathan, a 31-year-old man who describes himself as a tickle monster. [ laughter ] which i'm fairly sure is code for "unemployed sex offender." [ laughter ] [ cheers and applause ] there's a good lesson in there. if a grown man tells you he's a tickle monster, don't date him. call the police immediately. even elmo doesn't call himself a tickle monster. there you go, jonathan will be at home tickling his monster by week three. they already shot the show. they shot the whole season. rachel announced today she is very much in love and very much engaged. so i guess we don't have to watch, right? [ laughter ] one more thing before we forge ahead, it's thursday night which means it's time to bleep and blur the big tv moments of the week whether they need it or not. it is "this week in unnecessary censorship." >> i'm thrilled to be back at liberty university. i've been here, this is now my third time. and we love [ bleep ]ing [ bleep ]. right? we always [ bleep ] [ bleep ]s. we have no choice. >> does the president, he's [ bleep ], [ bleep ]. what do you think is going on? >> the president needs to [ bleep ] off here and let the investigation go forward. >> we are a group of people that is not ashamed to [ bleep ] other people up. >> a little boy got the chance of a lifetime to [ bleep ] the dutch chess of cambridge. it seems the moment was too much for the little [ bleep ] to handle. >> they're saying the real problem is not that trump might have blown an israeli spy, blew his [ bleep ], that is. >> how is it [ bleep ]ing a girl? is it tricky? >> let's get everybody to the phones. >> i hope you have a big [ bleep ]. >> i'd like to solve the puzzle. [ bleep ], [ bleep ] in my cabana. >> then there were three remaining, dr. johnson. maybe he's got the magic touch tonight, folks. [ cheers and applause ] >> jimmy: we have a good show tonight. "science bob" pflugfelder is here. we have music from linkin park. ann wilson is sitting in with the cletones, and we'll be right back with johnny depp. [ cheers and applause ] ♪ are you ok? what happened? dad kinda walked into my swing. huh? don't you mean dad kind of ruined our hawaii fund? i thud go to the thothpital. there goes the airfair. i don't think health insurance will cover all... of that. buth my fathe! without that cash from - aflac! - we might have to choose between hawaii or your face. hawaii! what? haha...hawaii! you might have less coverage than you think. visit aflac.com and keep your lifestyle healthy. aflac! and take an extra $10 offal day weekend sale when you spend $25 or more. save on summer styles you'll love and for a limited time get $5 kohl's cash for every $25 you spend. earn it on everything spend it on anything. only at kohl's. then moisturize with isaveeno® skin relief. with oat oil and natural shea butter, it softens and smooths extra dry skin and lasts for 24 hours. aveeno®. naturally beautiful results® play house of cards from netflix on the tv. wait, why did it start halfway through? did you watch it without me? -you did! -no, it was just ah... ok google, start over. -no idea what's gonna happen. -shhh! we, the device-loving people, want more than just unlimited data. we want unlimited entertainment. so we can stream unlimited action. punch unlimited robots. watch unlimited romance. if you're into that. but we also want more. like unlimited hbo. can i stop dying now? no can do mi amigo. it's unlimited. besides, you're really good at it james! don't settle for any unlimited plan. get at&t unlimited plus. and, now get the amazing iphone 7 on us. ♪ you might not ever just stand there, looking at it. you may never even sit in the back seat. yeah, but maybe you should. ♪ (laughter) ♪ but when we brought our daughter home, that was it. now i have nicoderm cq. the nicoderm cq patch with unique extended release technology helps prevent your urge to smoke all day. it's the best thing that ever happened to me. every great why needs a great how. ♪ >> jimmy: that's ann wilson sitting in with the cletones. that sounds so great, ann, really. you should come here every night, we would love to have you here doing that every night. >> thank you.

[ laughter ] i'm sort of standing there in this kind of pair littic shock. this guy's driving the bus, right? he looks at me and he goes, "chucks away, ginger." [ laughter ] saw him the next morning, he said the same thing. [ laughter ] >> jimmy: did you live in hollywood the first -- when you first moved to l.a.? did you live in this neighborhood? >> yeah yeah, i lived in a building the fountain right off -- it was yucca and whitley. >> jimmy: you moved out here, you were part of a band originally? that's why you came out, to play with the band. wound up getting into acting. did you have a regular job? or was the band paying your bills? >> no, there was no -- no, no, no. [ laughter ] you had to like pay clubs to play here. >> jimmy: you did? >> yeah, yeah. >> jimmy: you had to pay them? it wasn't like getting your friends to come and we'll let you play? >> there was that and you had to pay them. >> jimmy: how much would you have to pay? >> i don't remember. it was more than we had for sure. [ laughter ] >> jimmy: right. >> yeah, but i did have a job. the entire band got a job at this -- it was a telemarketing place. >> jimmy: what were you called? >> what were you selling? >> ink pens. >> jimmy: were they personalized? >> yeah. >> jimmy: aunt chippy did this too. what she described, tell me if it's the same. they would sell pens for a lot more than they were worth but over the phone they sounded great. like we'll send you a pen, it has your business' name on it, you can give to it your clients. they were like two bucks, $2.50 each. the people got the pens and inevitably they were furious because they were clearly not worth more than 5 cents. >> yeah, yeah. there was the -- yeah. we sold ink pens with their business name and everything. >> jimmy: that was the one. >> you'd do this whole -- there's a whole rap to it. but we had the extra added pleasure of offering them either a trip to greece -- [ laughter ] >> jimmy: really? >> or a grandfather clock.

[ laughter ] >> jimmy: were you good at it? >> i was not good at it. >> jimmy: not good at it. >> i did make one sale. the guy was going to buy like a gross of pens. >> jimmy: yeah. >> some inordinate, crazy amount of money. we're making the deal, i finally went, sir, don't. don't. don't buy these pens. [ laughter ] you're not going to greece, i can guarantee it. [ laughter ] that doesn't exist. and the grandfather clock, which does exist, is made out of pressboard. so like your dog, if your dog's tail wags against it -- >> jimmy: it's going down. >> it's going to come down. >> jimmy: did he thank you for your honesty? >> he did, in a confused way. i think he wanted pens. >> jimmy: did you get fired from that job? >> i took it upon myself to leave. >> jimmy: you fired yourself from that job, yeah. sounds like that was going to happen one way or the other. >> yeah. >> jimmy: you -- how old are your children now? >> oh, man. i believe rose is about to be 18. >> jimmy: okay. and your son is how old? >> 15. >> jimmy: are you teaching him to drive? as far as a 15-year-old? is that the time where you >> i'm not teaching how to drive. >> jimmy: because you don't think you'd bet'too early? does he golf? >> nope. >> nope. >> jimmy: johnny depp is here. with taltz, up to 90% of patients had a significant improvement of their psoriasis plaques. in fact, 4 out of 10 even achieved completely clear skin. do not use if you are allergic to taltz. before starting you should be checked for tuberculosis. taltz may increase your risk of infections and lower your ability to fight them. tell your doctor if you are being treated for an infection or have symptoms. or if you have received a vaccine or plan to. inflammatory bowel disease can happen with taltz. including worsening of symptoms. serious allergic reactions can occur. now's your chance at completely clear skin. just ask your doctor about taltz. are you one sneeze away from being voted out of the carpool? now's your chance at completely clear skin. try zyrtec® it's starts working hard at hour one and works twice as hard when you take it again the next day. stick with zyrtec® and muddle no more®. but the way we watch it is not. so, let's do something else. like what? like, watch tv wherever. what's that supposed to mean? it means, anywhere. in a car? yep. oof. but not like that. like this. oooh, family boat trip! yeah. and check this, record as many shows as you want. what? what? i just got chills. i know! tv, like, made for us. finally! finally. yeah. finally. ♪ wait, that's way cheaper than cable. >> der ist barrow -- >> spanish? >> aahh! >> ah, they're unable to stay on land. i knew that, though. >> ghosts! >> you will soon pay for what you did to me. >> there's no need to bother, really. i have no time to chat. >> i will be waiting. for you. >> why would you be waiting for me? >> jimmy: that's johnny depp in "pirates of the caribbean: dead men tell no tales."

[ laughter ] it was like the phone. they were like this. [ laughter ] because i think they'd already seen captain jack a few times on the ride. >> jimmy: yeah, they have a figure that looks like you on the ride, so they probably just thought -- yeah. well, foiled again. foiled again. >> that's the cheapest animatronic i've ever seen.
