V is for Violent Femmes
I did not realise this was an actual band. I remember them making a cameo on Sabrina the Teenage Witch and thinking they were a made u band for the show, I have been thinking this for years and then the other day I see a news article about them!
What is really weird is I find it hard to find any reference to them ever being on the show.
I also did not know when watching the show that the character Drell was played by Penn from Penn and Teller, not also then clocking Teller's guest appearance as a mute wizard.
It was again only years later when seeing Penn and Teller on TV that I recognised them and eventually made the connection!
