When I was in high school I was at practice and had an interesting experience. We were drilling cradles and I was the dummy. The other huy hit a standing cradle, threw me back, and the soft part of the back of my head hig the front of another guy's head. That's the last thing I remember until 2 hours later when I'm in the ER and they're trying to explain to me that I have a severe concussion.
Here's what I was told happened in between: Apparently when I hit I turned pale white. After laying on the mat for a minute the coaches came over to check on me and said "Will, are you alright?" I apparently stared at them, looked confused, and said "Water moccasain?" They started laughing until they realized I was serious. The rest of practice until my dad could come get me I was apparently laying in a corner to keep me upright and mumbling about robots, water sprinklers, and candy. My dad said all the way to the hospital I wouldn't shutup, just kept stringing together random words. To this day when I see the other guys who were there they will look at me and say "Water moccasain?"
