the only head injuries I've sustained were pimples and blackheads

We did have a couple who were going out in high school that both got concussions within a few months of one another. One was a football player who got it by flying off a four-wheeler (fortunate for him there wasn't a telephone pole. Another kid from school died from flying off his four wheeler into a phone pole), but his then-girlfriend got hers by slipping in the bathroom before a football game and bashing her head on the tile floor.

it was kinda funny at the time xD
