My older brother worked at a local Ski Resort while in HS, and the owner would pay the boys in cash, counting it out in front of them. One evening after work he was counting the money out to pay them and one of the boys started interrupting him by asking questions. The answer always involved a number and the boy would wait till the owner was well past the number that was the answer. The owner would answer and then continue counting, but starting with the number that was the answer to the question. The boy did this several times, and I don't know how much he actually got, but it was a lot more than the pay should have been. I don't think the other boys had the nerve to try it, but I'm sure they thought it was funny.
