>> alisyn was concerned that we haven't checked our numbers because we could be sitting on at least $1,000 or something. you say there's some $2 billion in unclaimed prize money annually? >> that's right. and we encourage players, just because you didn't win the big one, don't throw that ticket away. check that ticket. you can go to any retailer and check that ticket as well. we want to pay those prizes, michaela, don't let them go unclaimed. >> what happens if they don't? what happens if the six months goes by, what happens to the money? >> all unclaimed prizes go back to public education. it depends on what state in which you purchased the ticket. >> just because because we are a news organization, on the flip side, a lot of news made of this being $1.6 billion. a lot of changes to up the size of the jackpot. is this sustainable, though?
