oh, i'm on. i'm sorry, i was enjoying listening to you snort. [ laughs ] levine: they gave him the "late night" show after "the tonight show," and at the time, people thought, who's gonna watch television at 12:30 at night? who's up? i'll tell you who's up. young people. college people. is it going well? i know this is the first show and i think this guy needs a little support. dave letterman. mandabach: he was antiestablishment at his core. he was thumbing his nose to any existing social structures. lettermen: who are those women out there, by the way? woman: neighbors. i'll get rid of them. hey, excuse me. just keep it moving, come on. he kind of spoofed the whole notion of talk shows. it's the "late night" guest cam. please say hello to tom hanks. here he is. [ cheers and applause ] hanks: no one can go on the "david letterman show" and try to steer it towards a point of view or push something in particular. he just wouldn't stand for it. you're on to do one thing and one thing only -- be as funny as the rest of the show.
