If you're in NYC and you're a fan of the Late Show with David Letterman, why not try to get on the show?
You can submit a request for tickets online at their website, or you can visit the theatre and request tickets in person.
They choose people randomly to receive tickets, so don't worry about waiting in line early, because it won't work. If they grant you tickets, they'll let you know by phone.
Keep in mind that they don't allow anyone under 18 to attend the show.
If you can't get tickets, try hanging out at the Hello Deli, which is right next to the Ed Sullivan Theater (where the Late Show is taped). Dave often pops in there during a taping, and you may wind up on TV!
