What's the funniest song you ever heard?

Twisted Tunes.com did a cover of Hootie and the Blowfish's "I only wanna be with you" changing it to "I only have a 3inch tool" The lyrics are great and will make anyone laugh. In fact, there is a lot of funny songs there. http://www.twistedtunes.com

"They're coming to take me away" by Napoleon XIV. Funny enough by itself but the flip side on the original 45 rpm release is the same "song" backwards. That's funny.

Somebody did a song about Gary Hart right after it got out that he slept with...an intern? I can't remember who. I'm told John Denver did the song at some concerts, and a lady was nice enough to send me a tape of it, which I've long since lost. Anyway, HILARIOUS song!!

If anyone happens to know where I can find it, I'd be both amazed and appreciative!
