4. Walter Wood
Pro Skier Walter Wood goes on the half pipe wearing nothing but a thong. Not the best time to crash in the snow.
3. Lady Gaga
Lady Gaga yaks on stage in front of the entire audience. But good for her for continuing to perform!
2. Justin Bieber
The Biebs also gets sick on stage, but unlike Gaga, he runs off stage like a baby.
1. Harry Styles
Last but not least, One Direction’s Harry Styles got hit in the nuts by a shoe that someone from the crowd chucked at him. Ouch.
