Jew and an Arab go into a bakery.
The Arab steals 3 pastries and puts them in his pocket.
He says to the Jew, "See how good I am? The owner didn't see anything!"
The Jew says to the Arab, "I am going to show you there is nobody better than a Jew stealing."
He goes to the owner 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 ask for another one.
The owner gives him another one. Then the Jew asks for another one and swallows it just the same.
The owner is starting to wonder where the magic trick is and says,
"What did you do with the pastry? Are you trying to fool me?"
The Jew answers "Look in the Arab's pocket."
