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.
