The note reads: "5 lamb chops, please." Amazed, the butcher takes the money, puts a bag of chops in the dog's mouth, and quickly closes the shop.

Curious, he then 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. After a while the dog pushes the "stop" bell, then picks up the bag of meat and gets off the bus. The butcher also gets off the bus and follows the dog.

The dog then trots down the street and stops at a tobacco stand and buys a newspaper. Then he turns up another street, rounds the corner and comes to a house. Before going in the driveway, the dog checks the mail and takes out some letters and then goes up the steps of the house and drops his bag on the step.

The dog then rings the doorbell and waits, but there is no answer. He then goes to the window and looks in and barks, but still there is no answer. So he goes back down the driveway, takes a big run, and throws himself against the door. He does this again and again.

Finally, a man opens the door and starts cursing and shouting at the dog. The butcher runs up and screams at the guy: "What the hell are you doing? This dog's a genius! I saw him buy the meat, newspaper and even check your mail"

The owner looks at the butcher and says, "Genius, my ass.... It's the second time this week he's forgotten his keys!"
