One of the "classic" trivial puzzlers is the one about the three hotel guests who each paid $10 for the room: Total $30.

The manager decides that 3 guys in a room is a bit much, so he gives the bellhop $5 to return to the 3 guys.

The bellhop can't figure out how to split the $5 three ways, so he gives each of the guests $1 and pockets the remaining $2.

Now each guest paid $10, but got $1 back, making the total paid by the guests 3 x $9 = $27. The bellhop kept $2, which makes $29.

What happened to the other $1?????

(There are numerous variations.)
