At The Vets

A man takes his Rottweiler to the vet. “My dog is cross-eyed. Is there anything you can do for him?”

“Well,” says the vet, “Let’s have a look at him.” He picks up the dog and examines his eyes, then he checks his teeth. Finally, he says, “I am going to have to put him down.”

“What? – because he’s cross-eyed?"

“No, because he’s really heavy.”
