On a visit to New York, an Englishman and a Scotsman go to a pastry shop. The Englishman whisks three cookies into his pocket with lightning speed. The baker doesn't notice.
The Englishman says to the Scotsman, "You see how clever we are? You'll never beat that!"
The Scotsman says to the Englishman, "Watch this, a Scotsman is always cleverer than an Englishman."
He says to the baker, "Give me a cookie, I can show you a magic trick!"
The baker gives him the cookie which the Scotsman promptly eats. Then he says to the baker, "Give me another cookie for my magic trick."
The baker is getting suspicious but he gives it to him. He eats this one too. Then he says again, "Give me one more cookie."
The baker is getting angry now but gives him one anyway. The Scotsman eats this one too. Now the baker is really mad, and he yells, "And where is your famous magic trick?"
The Scotsman says, "Look in the Englishman's pocket!"
