I'll say it again: Tom Hanks is a national treasure. Here's a clip from his appearance on the Late Show, in which he pokes fun at his habit of making historical mini-series on HBO by announcing his latest pet project: an 11-part series on the creation of the Pop Tart. He plays Bert Loomis, without whom we may have never had Preston Meyers developing a crush on Jennifer Love Hewitt in Can't Hardly Wait.
