As a butcher is shooing a dog from his shop, he notices a $10 bill and a note in the dog’s mouth that reads: “5 lamb chops, please.”
Amazed, he takes the money, puts a bag of chops in the dog’s mouth, and quickly closes up shop to follow him.
He watches in awe as the dog waits for a green light, looks both ways, and trots across the road to a bus stop. The dog checks the timetable and sits on the bench. When a bus arrives, the dog walks to the front, inspects the bus number, and hops on.
Dumbstruck, the butcher boards too, following the dog as the bus travels to the suburbs. After a while, the dog stands on his back legs, pushes the “stop” bell, and gets off. The butcher follows closely.
The dog runs up to a house, drops the bag of lamb chops on the doorstep, and backs up. He takes a big run and whap! slams into the door. No answer.
The dog repeats the process—slamming into the door several times—then jumps on a wall, circles the garden, beats his head against a window, and jumps back down, waiting at the door.
Finally, a big guy opens the door and starts cursing and shouting at the dog.
The butcher, furious, runs up and yells, “What the hell are you doing? This dog is a genius!”
The owner replies, “Genius, my ass… it’s the second time this week he’s forgotten his keys!”
