The Artist: Drake
The Fall: Just a short time after Drizzy reportedly injured his ACL, he went against his doctor's orders and tried performing in New Jersey in July 2009 and collapsed on stage while performing "Best I Ever Had." He had to be carried off stage because he couldn't walk off under his own power.
How Embarrassing Was It? In reality, Drake's ACL injury was no laughing matter. But, at the time, no one knew why Drake fell, so the crowd seems to share on big collective "WTF?" when he goes down here. You'd be better off listening to your doctors next time, Drake.
