Back in grade school there was a big razor blade apple scare one year. Apparently a kid in another school actually bit into an apple with a razor blade in it. There was a letter that we had to bring home from school to our parents to warn them about it. Years later I was talking with a friend about stupid things we did as a kid. He told me how he took a bite out of an apple and then stuck a razor blade into it and showed it to his parents as a joke. They freaked out and called the police. It was funny to find out that such a famous story at my school started as just a joke a kid was playing on his parents.
