We are deeply saddened by the untimely death of Jackass star and funny man Ryan Dunn. Dunn died early this morning, after his Porsche 911 slid off a Pennsylvania road and crashed into a tree. Earlier in the night Dunn posted a picture of himself drinking with his friends, which most likely aided his fatal crash. So in honor of all of the wild and crazy stunts Dunn performed, during his short-lived Jackass career, here are some of the craziest and wildest sports collisions of all time.
