I'm not a big fan of Fallon, but he has a few things that work. One of his bits is when a joke bombs (was anyone better than Carson? he'd hit the microphone to make sure it was on, or he'd look to the side with that weird facial expression...)
Well, Fallon takes the cue card with the joke on it, and gives it to an audience member. I have to assume that some of the audience members that have received these, get them autographed later. I know I'd try to do that.
Anyway, his joke involved the Obama's re-decorating the White House. He said something about them putting a nice painting up, in place of where President Bush had the autographed cast poster from The Dukes of Hazard.
