A Jew and an Arab go into a bakery. The Arab steals three pastries and puts them in his pocket. He says to the Jew, "See how slick I am? The owner didn't see anything."
The Jew says to the Arab, "That's dishonest of you. I am going to show you an honest way to get the same result."
He goes to the owner of the bakery and says, "Give me a pastry and I will show you a magic trick." Intrigued, the owner accepts and gives him a pastry. The Jew swallows it and asks for another one. The owner gives him another one. Then the Jew asks for a third pastry and eats that, too.
The owner is starting to wonder where the magic trick is and asks, "What did you do with the pastry?"
