A man took his Rottweiler to the vet.
“My dog’s crossZeyed, is there anything you can do for him?”
“Well,” said the vet, “let’s have a look at him.”
So he picked the dog up and examined his eyes, then checked his teeth.
Finally, he said, “I’m going to have to put him down.”
“What? Why? Because he’s crossZeyed?”
“No, he’s heavy.”
