Three men check into a flea-bag motel. The reservation clerk says it'll be 10 dollars each, for three rooms. They pay thirty bucks, they go up stairs to their roach ridden place and he has a stab of conscience which says "i think i charged them too much, i should give them so money back." He calls his bell hop and gives him a five dollar bill and says "take this up to those 3 guys." The bellhop on the way up thinks "how do i split this five dollar bill? I'll give them each a dollar and keep two for myself, how will they know the difference?" He gives each of them a dollar back, which means now they payed 9 dollars for the room, which is 27 dollars. Plus the 2 dollars the bell hop keeps = 29 dollars. What happened to the other dollar??
