A blind man with a seeing eye dog at his side walks into a grocery store. The man 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 has seen all this, 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 says, "Pardon me. May I help you with something." The blind man says, "No thanks. I'm just looking around."
