My favorite off-camera memory of Jon Stewart is watching him jump from the second level of a tuna tower into the waters off Grand Cayman.

Simply being a guest on David Letterman's show has been a highlight of my career. I never dreamed that I would follow in his footsteps, though everyone in late night follows Dave's lead. I'm thrilled and grateful that CBS chose me. Now, if you'll excuse me, I have to go grind a gap in my front teeth.

I'm a junkie for exhaustion, and I'm a junkie for setting up my expectations too high and then trying to meet them.

I like to do things that are publicly embarrassing, to feel the embarrassment touch me and sink into me and then be gone. I like getting on elevators and singing too loudly in that small space. The feeling you feel is almost like a vapor. The discomfort and the wishing that it would end that comes around you.
