Steve Martin in the 70's. His "Let's Get Small" album was brilliant. "Wild and Crazy Guy" was great too; the second half was probably much better if you were in the audience for that. It also had a recording of "King Tut" so it was good in my books. "The Steve Martin Brothers" I never got to buy (it's the only one that hasn't been converted to CD), but I also own his last stand-up album, "Comedy Is Not Pretty," which is his second best album.
"Mind if I smoke?"
"I don't know..... do you mind if I fart?"
Steve Martin is the best.
Robin Williams is good too. He's a bit vulger though.
