Disappearing Dollar

Three guys go into a hotel and ask for a room.

The Hotel owner says, "I only have one room left, but you guys are welcome to share it. It’s $30 a night."

They are desperate so they take it for the night and they each give him $10.

As they go up to the room the owner tells the bellboy, “I accidentally overcharged them. The room is only $25. Here, give them $5 back to them." and hands him 5 singles.

The bell boy puts $2 in his pocket and says "Excuse Me, Gentlemen! You were accidentally overcharged. He is your change." and hands each guy a $1 bill.

With each receiving $1, they have now paid $9 each for the room. $9 * 3 = $27.

The Bellboy has $2 in his pocket. $27 + $2 = $29
