3 meatheads go to a hotel, of course they only need one room, so that's what they ask for.
but the desk clerk had to take a leak so a bellhop is covering him. the bellhop charges them $30, so each meathead kicks in $10. when the clerk comes back, he tells the bellhop he over charged them by $5. so he gives $5 to the bellhop and tells him to return it to the meatheads.
on the way to the room, the bellhop figures they won't know the difference and decides to keep $2 for himself. so he goes to the room and gives them $3.
so each meathead gets $1 back, their final cost is $9 each.
3 x $9 = $27
plus $2 the bellhop took = $29.
what happened to the other dollar?
