A large dog walks into a butcher shop, carrying a purse in its mouth. He puts the purse down and sits in front of the meat case.

"What is it, boy?" the butcher jokingly asks. "Want to buy some meat?"

"Woof!" barks the dog.

"Hmm," says the butcher. "What kind? Liver, bacon, steak..."

"Woof!" interrupts the dog.

"And how much steak? Half a pound, one pound..."

"Woof!" signals the dog.

The amazed butcher wraps up the meat and finds the money in the dog's purse. As the dog leaves, the butcher decides to follow. The dog enters an apartment house, climbs to the third floor, and begins scratching at a door. With that, the door swings open and an angry man starts shouting at the dog.

"Stop!" yells the butcher. "He's the most intelligent animal I've ever seen!"

"Intelligent?" counters the man. "This is the third time this week he's forgotten his key!"
