not exactly in "sports".
We were learning about alcohol abuse one week, and we got to wear these alcohol simulating glasses.
The object was to catch a ball using the "10-15 beers" glasses. I caught the ball, but it bounced out of my hand. I jumped for it, slid onto the floor, and bashed my face right into a locker. THEN, when i got up, i accidentally wandered into the wrong classroom, where a bunch of fifth graders looked at me like a had a running chainsaw in my hand.
i hated that year of school.
