A dog walks into a butcher's shop carrying a small bag which he puts on the counter. The butcher opens it to find a note asking for 2 pork chops and some money. He puts the chops in the bag and takes out the right money. The dog leaves and the butcher amazed quickly locks the shop and starts to follow the dog. The dog walks down the road to the bus stop, looks at the timetable and sits on the seat. When a bus arrives the dog walks to the front, looks at the number and returns to the seat. When the next bus arrives he walks to the front, checks the number, gets on the bus, gives the driver his bag and the driver takes out the money and puts his ticket in the bag. The dog then sits on a seat and looks out the window during the journey. After 4 stops the dog rings the bell and gets off the bus followed by the butcher. The dog walks down a number of roads until it comes to a house where he walks up the path, stands on his hind legs and rings the bell and waits. When no one comes he rings again. When no one still comes he walks down the side of the house, barks loudly and then goes back to the front door and waits. The door opens and a man starts shouting at the dog. "Don't shout at him" says the butcher, "he's a genius". "Genius my foot. That's the second time this week he's forgotten his key!"
