Last night I saw Richard Lewis at the Improv. Hilarious, of course, though the set was quite short. He's 58 years old but still sharp. He mentioned that season 5 of Curb has a lot of stuff with him in it, and that it is quite dark. He took about 5 minutes to come out after the host announced him. The "m" in "Improv" kept coming unstuck from the wall, and he kept pressing it back down, which was pretty funny. And he had trouble with his tape recorder.
A month or two before, I saw a guy named Joey Diaz. He was in the remake of The Longest Yard. I think his entire act was about sex, mostly oral. It got old quick, though we were sitting right in front of the stage, so we had to pretend to enjoy it, which was bizarre.
