The clerk, after showing to her an assortment of pit-bulls, Dobermans, etc. ranging from $500-2000, produces a tiny poodle with an asking price of $5,000.

"Why is the poodle so expensive?" asks the lady.

"Well, madam, this dog knows karate. Please let me demonstrate" says the clerk. He produces a large cinderblock. He shows it to the poodle and says "Karate the block", which causes the poodle to attack the cinderblock and turn it to dust.

Then, the clerk shows the dog a large log and says "Karate the log!" The poodle quickly turns the log into toothpicks.

The lady is really impressed, buys the poodle and takes it home inside her bag.

Her husband asked her if she found a dog.

The lady produced the poodle from her pouch.

"How much did you pay for this mutt?" asks her husband.

"Well, I paid $5000, but you must know, this dog knows karate!" informs him his wife.

And the angry husband says "Karate, my ass . . ."
