He says to the white, "See how good I am? The owner didn't see a thing." The white man says to the black man, "That's typical of you black people. 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 white man swallows it and asks for another one. The owner gives him another one. Then the white man swallows that one and asks for a third pastry and eats that, too.
The owner is starting to wonder where the magic trick is and asks, "So what did you do with the pastries?"
The white man replies, "Look in the black mans back pocket....."
