Hammer Throw Fail

Can someone explain to me what the hell the hammer throw is?

It’s not a hammer. They should call it the ball on stick throw.

Anyway, this Canadian high school kid is filming his hammer throw and falls right on his back. I almost feel this video is a goof, because he is throwing this thing in his driveway. Where is he expecting to throw this thing?

Definitely in the running for the funniest video of the week.
