A dog walks into a butcher shop with a wallet strapped to his neck, and approaches the displays. He waits for a man to finish his order, then the butcher leans over the shelf and asks,
"What'll you have?"
The dog places his paw in front of the ground beef, so the butcher asks how many pounds? The dog barks twice, so the butcher packages 2 pounds of ground beef.
The man watches as the dog moves in front of the pork chop display, and places his paw in front of them.
"How many do you want? asks the butcher.
The dog barks four times so the butchers packages 4 chops. The dog walks over to the cash register to pay, so the butcher removes enough cash from the wallet to pay for the meat. The dog picks up his packages in his mouth an leaves.
Intrigued the man follows the dog several blocks until he walks up to a house and scratches on the front door. His owner answers, and lets the dog in.
"That's an amazing dog you have there!" the man from the butcher shop marvels.
"Not really," the owner frowns. "That's the second time this week he's forgotten his key!"
