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?''
