David Letterman has been on the air for a long time, and he's developed a lot of funny bits over the years. He's spent time dropping things out of windows, sharing dumb pet tricks and goofing around with sidekick and band leader Paul Shaffer.

Lots of actors, musicians, sports stars and even politicians have delivered their top ten answers to some question over the years, but this week marked new territory for the bit -- cartoons.
As you can see below, Simpson patriarch (and doughnut enthusiast) Homer J. Simpson stopped by New York to deliver his top ten reasons he's proud to be an American.
