A man took his Rottweiler to the vet and said to him, My dogs cross-eyed. Is there anything you can do for it? Well, said the vet lets have a look at him The vet picks the dog up by the ears and has a good look at its eyes. Well, says the vet Im going to have to put him down. Just because hes cross-eyed? says the man. No, because hes heavy, says the vet.
