I think that you can find a lot of humor in music. They Might Be Giants are a howl. Tell me you didn't laugh when you first heard the B-52's or Devo. I remember seeing Elvis Costello on SNL waaaay back before he was known at all outside of some New York clubs and thought he was just an act like the Blues Brothers....etc. Lou Reeds' 'Take a walk on the wild side' has some funny lyrics. Sad but funny at the same time. Ray Charles 'Hit The Road Jack' and 'What I say?' Maybe it's just me, but I think 'Walk this way' is a very funny song. Never fails to make me laugh.

And the blues have some of the funniest lines of all time in their lyrics. 'My woman so cold, when she opens her mouth a light comes on...Frigidare woman...."

Etc...etc.

And one of the funniest stand-ups working today is a kid named Stephen Lynch. It's just him, his guitar and some of the most twisted and hilarious lyrics you have ever heard. :)
