Three guys walk into town. They go into a hotel and ask for a
room they can share. The clerk has just the thing they want for
thirty dollars. The clerk sends them to the room, takes out the
ledger, and realizes that he made a mistake. The room costs only
twenty-five dollars. Now he has to divide five dollars evenly three
ways. Can't be done. So the clerk pockets two dollars, tells the
guys that he made a three dollar mistakeand gives them each a
single. Now, each man paid only nine dollars for his share of the
room. Nine times three equals twenty seven, plus the two in the
clerk's pocket equals twenty nine. Where's the other
dollar?
