A man took his Rottweiler to the vet and said "My dog's cross-eyed, is there anything you can do for him?"
"Well," said the vet, "lets have a look at him." So he picks the dog up and has a good look at its eyes.
"Hmm," says the vet, "I'm going to have to put him down"
"Just because he's cross-eyed?" says the man.
"No, because he's heavy," says the vet.
