A man takes his Rottweiler to the vet.
"My dog's cross-eyed," the man says. "Is there anything you can do for him?"
"Well," says the vet, "let's have a look at him."
So he picks the dog up and examines his eyes and ears and then checks his teeth. Finally, he says, "I'm going to have to put him down."
"What?" The man was astonished. "Why? Because he's cross-eyed?"
"No," said the vet, "because he's really heavy!"
