Bizarre injuries you've suffered

[OrigamiSensei]

I was bitten on the head by a flying human, at least that's the entertaining way to describe it.

It was in 7th or 8th grade gym class and we were doing gymnastics. I had just done a run on the mini-trampoline and made a landing on the pad when suddenly I was slammed from above. Some other moron kid had decided he was going to leap from the bleachers and land on the mini-tramp landing pad but he wound up driving his teeth into my scalp instead. It left a nasty semi-circular scar on my head. The other guy knocked out a tooth.
