Harold's new job had him working really late. He decided to get his wife a watchdog. So he went to the pet store and asked for a doberman.

The employee said, "If it's a guard dog you want I have a dog just for you."

The man walked to the back of the store to get a dog and came back with a little poodle.

Harold said, "Seriously? This small thing, a watch dog? You're kidding, right?"

The employee said, "No, this dog is special; he knows karate."

"Karate? I don't believe it," Harold said.

The employee put the dog down and said, "Karate the sign."

He pointed to a sign advertising dog food. The dog ran up to the sign and ripped it to shreds.

Harold was amazed at this.

The employee then said, "Karate the chair," pointing to a chair in the  corner. The dog ran to the chair and ripped it to shreds.

By now Harold was convinced. He bought the dog and brought him home.

When he got home, he surprised his wife with his thoughtful gift, but she had the same doubts as Harold had had. She said, "This little thing, a watch dog? No way."

Harold said, "Honestly, love. This dog knows karate!"

"Karate," she laughed, "Karate my ass!"
