So I'm a 6th grade teacher and we get lot of funny stories but one that I remember recently was that we caught a kid who was stealing all the leftover apple juice and orange juice containers after breakfast and dumping them into his bag.  Throughout the day he was selling them to thirsty kids for a quarter a piece. When we caught him he told he had been doing it for 3 weeks and had made over 200 dollars but he said it was annoying keeping up with it because it was all in quarters.
