Steve Landesberg: (on his topical comedy routines)I talk about politics, music, sports. I try to keep current and talk about what's happening. Sometimes what I do...tonight might be gone already tomorrow. And the audience lets you know that. You think, "I just got a big laugh with that yesterday. Where did it go?"
