A blind man, with a seeing eye dog at his side, walks into his local grocery store. He walks to the middle of the store, picks up the dog by the tail, and starts swinging the dog around in circles over his head.The store manager, who up until this point thought he had seen it all, thinks this is quite strange. So he decides to find out what's going on. The store manager approaches the blind man swinging the dog and asks, Pardon me. May I help you with something? The blind man replies, No thanks. I'm just looking around.
