Sam and George owned a store in the outskirts of San Francisco. It had been burglarized several times in the past year and Sam decided to buy a guard dog.

Shopping for one, Sam found himself in Chinatown, at a pet store whose sign boasted, The Best Guard Dogs That Money Will Buy. He entered the store, but much to his disappointment, all the dogs he could see were Pekingese.

"Excuse me", Sam said to the manager, "But the sign outside says you sell guard dogs. Where are they?"

The manager, an elderly Chinese, replied, "Oh, but these are highly trained guard dogs. They all know karate."

"Karate! No way."

"I'll show you", said the shop owner. He took one of the Pekingese out to the backyard and put it in front of a brick. The dog stood absolutely still. The shopkeeper gave a command, "Karate! Brick!"

And with complete astonishment, Sam saw the little dog perform a perfect karate chop, splitting the brick in half. Totally amazed, he bought the dog. Back at his own store, he showed the guard dog Pekingese to George, who thought he was completely mad and told him to return the Pekingese immediately.

"But, he is a trained guard dog."

"Yeah, sure!"

Sam put the Pekingese on the floor and said, "He knows karate!!"

With a sneer George retorted, "Karate! My Foot!"
