Ok here is the basic story

Three men decided to split the cost of a hotel room. The hotel manager gave them a price of $30.

The men split the bill evenly, each paying $10, and went to their room. However the hotel manager realized that it was a Wednesday night, which meant the hotel had a special: rooms were only $25. He had overcharged them $5.

He called the bellboy, gave him 5 one-dollar bills and told him to return it to the men.

When the bellboy explained the situation to the men, they were so pleased at the honesty of the establishment that they promptly tipped the bell boy $2 of the $5 he had returned and each kept $1 to himself.

So each of the three men ended up paying $9 (10 minus 1) totaling $27, plus $2 which makes $29.

WHERE DID THE EXTRA DOLLAR GO???

Well known misuse of math but still puzzles people if presented convincingly.

The hotel room only cost 25 $ Thus 27 $ (9 * 3) - 2 ( that the bellboy kept) = 25 $ and everything is as it should be.

This is not hard. The way it is worded can trick people.

And to bring this back into magic, Daryl had a routine where a dollar bill vanishes as he tells this story. It appeared in his 1992 lecture notes (which he was still selling in '96, when I bought them).

I believe it also appeared in Labyrinth.

No, my mistake. I meant Dan Harlan's and Marv Leventhal's former magazine the Minotaur. [A classical education gives rise to its own oddly distorted recollections.]
