Three guys walk into a hotel and decide to split the cost of a room. The room is $30. They each pitch in $10 and head up to their room. The manager gets wind of it and tells the clerk the room is only $25. He hands five $1 bills to the bell hop and tells him to refund the guys' money. On the way up to the room, the bell hop gets to thinking, as bell hops are wont to do, and says to himself, "No way can three guys split $5, I'm going to help out." He stuffs $2 in his pocket, knocks on the door, gives each guy back a buck and heads back downstairs to the desk, glowing in the warmth of a job well done. So now each guy has paid $9. $9 times 3 is $27 plus the two the bell hop stole - only $29! Where is the other buck? EDIT: Solution [url=http://www.bungie.net/en/Forum/Post/71534185/0/0/1]here[/url].
