As a butcher is shooing away a dog from his shop, he sees a $25 bill and a note in his mouth, reading: “10 pork chops, please.”

Amazed, he takes the money, puts a bag of pork chops in the dog’s mouth, and quickly closes the shop. He follows the dog and watches him wait for a green light, look both ways, and trot across the road to a bus stop. The dog checks the timetable and sits on the bench. When a bus arrives, he walks around to the front and looks at the number, then boards the bus. The butcher follows, dumbstruck. As the bus travels out into the suburbs, the dog takes in the scenery. After a while he stands on his back paws to push the “stop” bell, then the butcher follows him off. The dog runs up to a house and drops his bag on the step. He goes back down the path, takes a big run, and throws himself -WHAP!- against the door. He does this again and again. No answer. So he jumps on a wall, walks around the garden, beats his head against a window, jumps off, and waits at the front door. A big guy opens it and starts cursing and shouting at the dog. The butcher runs up and screams at the guy: “What in hell are you doing? This dog’s a genius!” The owner responds, “Genius, my ass… It’s the second time this week he’s forgotten his keys!”
