The Dead Milkmen were the subject of the only really funny joke on Beavis and Butthead, when the boys watched their video Smoking Banana Peels.

Beavis: What is this?
Butthead: It's college music.
Beavis: Does it suck?
Butthead: Beats me.

According to an article I once read in some alternative newspaper, the Dead Milkmen began as a joke by the writers of a Philadelphia zine. A couple of them wrote about the band's fake music and tour dates, and readers started to complain that they couldn't find any of the bars where the band was supposed to play, and so they got a couple of musicians together and started playing. The result was a decent-sized pile of pretty funny albums.
