9. Poison at MTV Video Music Awards, 1991 - Cocaine
Poison weren't exactly the coolest band in the world in 1991, and their disastrous performance at the MTV Video Music Awards that year did little to earn them new fans. The were supposed to play "Unskinny Bop," but guitarist C.C. DeVille – then in the midst of a horrible cocaine addiction – went into "Talk Dirty to Me" instead. At one point, his guitar became completely unplugged. It was a huge moment for the band, and they absolutely blew it. Bret Michaels and C.C. had a huge fight backstage, and the guitarist was fired. He returned five years later.
