What's the funniest song you ever heard?

Zappa's "Honey Honey Hey, Baby Don't Ya want a Man Like Me?' Sample lyric: "He trys to start the car, but the battery's dead; So he asked to use the phone, and she gives him some head...and thats the end of our story!"
Titties and Beer, another classic,as well!

I was in Denver 10 years ago and I heard a song on the local jazz station called:

"An Ugly Woman Told Me No"

...it was hilarious and I never found out who sang it, I only heard it once.

Randy Newman's "Short People" was a hilarious song also.

Oscar Brown Jr. has a tune calle "But I Was Cool" that will crack you up.

Zappa's "We gotta stick together", "Catholic girls",

I agree with Frank Zappa (adding "please don't eat the Yellow Snow"), Randy Newman (adding "Short People") and various Dr. Hook. I'd also add Warren Zevon (e.g. "Werewolves of London") and Tonio K (e.g. "Life in the Foodchain", "H-A-T-E-R-E-D").

Tom Lehrer's "That was the week that was" album - every song is a hoot, though my particular favourites are "New Math", "The Vatican Rag", and "Pollution". Also, try to check out the "Stairways To Heaven" album. Eleven different versions of "Stairway To Heaven", my favouite is the Australian country version.

"Didn't You Kill My Brother" by Alexei Sale is also pretty funny in a twisted sort of way, as is "Cousin Dupree" by Steely Dan.
