A policeman is walking down the road when he sees a man with a brick tied to a dog leash. He decides to go and humor him. He walks up to the man and says, ”Hello, sir, I like your dog!”

The man looks at the brick, then the policeman, and says, ”It’s not a dog, it’s a brick.”

The policeman replies, ”Oh, sorry, I thought you were a bit mad,” and walks off rather puzzled.

As the policeman goes out of sight, the man turns to the brick and says, ”That fooled him, didn’t it Rover?”
