Kid Cudi on 'One Tree Hill' and Other Musicians on Bizarre TV ShowsNot every musician acts with the abandon and bravado of, say, Kanye West, but others can still make you scratch your head, like when they make bizarre cameos on random TV shows. Case and point: rapper Kid Cudi appearing on CW's yes-it's-still-on 'One Tree Hill.' We don't ask why musicians do it, but it's fun to catalog them, and there have been a lot of head-scratchers over the years. Some make sense, like Britney on 'Glee,' but others are just flat out bonkers like Boy George on 'The A-Team.' It's crazy and oddly amusing at the same time, so check out our list of the weirdest TV spots by musicians.
