The Personal Injury Warning System chronicles Jonathan Corum’s lifetime of injuries, from the creation of his bellybutton to a parasite in his small intestine. Each incident has its own clever warning symbol, which I suppose could be used to warn others away from similar injuries if we were a little more clairvoyant. (Thanks to Lisa, who is working on her own “thumb injured by freak yogurt accident” symbol. Perhaps she needs to eat less pointy yogurt.)
