The internet is FREAKING OUT about the fact that Justin Bieber barfed on stage this weekend, but he isn't the first performer to do that. Eminem did it on purpose, as part of his show (with sound effects, not actual vomit). Blessthefall's singer puked on his fans, this kid puked on his peers, singer of the hardcore band the Carrier puked at a show in Philly and kept playing. Hey, it happens!

So, of course, it begs the question: Who has the best barf? Watch the clips (so long as you don't have a weak stomach) and vote for your favorite upchuck on Line Out!
