List Rules
Vote up the most inexplicable appearances from music stars.

Just like movies, TV shows are full of cameos from musicians. For many, like Usher or Lance Bass, these appearances coincided with the release of an album or a major song. For others, this is an opportunity to perform against their established brand, as Justin Bieber did on CSI. Others approached it as an acting challenge like Dave Matthews did when he guest starred on an episode of House. And then, there's Flea, who's essentially just a character actor at this point… but that doesn't mean it isn't surprising when he shows up in a galaxy far, far away.

Here are a few random musician TV cameos that made us do a double-take. Make sure to vote up the ones you think are totally, completely random!
