Years ago my uncle had a person stealing from lockers and lunch boxes.He had an idea about who it was and set a trap.He called the foreman to the locker room and explained what trap he set. After coming in to the locker room he said loud enough for everyone to hear that his wife made two roast beef sandwiches and a big piece of chocolate cake.When everyone left the locker room a few minutes later they heard a scream,trap worked.There stood the biggest guy in the crew by my uncles locker with a rubber snake hanging from a string,scared the hell out of him.
