glasskey14, here's the mind boggling mathematical problem I was talking about:
Three men walk into a hotel and each of them pay $10 for a room ($30). They go into their rooms when the manager decides that $30 is too much. He asks a bell boy to return $5 to the men (not each, just $5). Since you can't spilt $5 the bell boy keeps $2 and returns $3 to the men ($1 each each person). So now it works out to where each man paid $9 for a room. 9 times 3 equals 27 so $27 dollars overall. Than the bell boy kept $2 so $27 plus $2 is $29...where did the other dollar go?
