Anal Cunt always come up in these threads. Only a handful of their songs are actually funny beyond their titles though. I used to have "Hootie And The Blowfish" as my ringtone, when I was at work I'd jump to open my phone during the slow bit - thank fuck they couldn't make the lyrics out anyway.
My personal favourite is "We Threw Gasoline On the Fire And Now We Have Stumps For Arms And No Eyebrows" by NOFX.
