Note: This one is an interesting little brain teaser, see how soon
can you find the answer :)

Put on your thinking caps, because this one's going to hurt...

Three sailors walk into a motel and ask how much it would cost to
spend the evening. The manager tells them that it will cost $30 for
all three.  Each sailor gives the hotel manager $10.

Later, the manager realizes that he made a mistake. Because it is a
weekday, the cost is $25, not $30. He gives $5 to the bell-boy and
tells him to return the money to the sailors.

The bell-boy decides to keep $2, and returns the remaining $3 to the
sailors  - - $1 to each sailor.

Each sailor paid $10 but was refunded $1, netting $9 each.
$9 times 3 (number of sailors) equals $27.
$27 plus the $2 that the bell-boy kept equals $29.
Who the hell has the last dollar?
