man goes to the vet with his pet rottwieler, vet asks, "whats the problem?" man says, my dog has cross eyes, vet says, lets have a look at him, so he picks the dog up, examines his eyes and teeth, he turns to the man and says, i am going to have to put him down, man says why? for having cross eyes?? vet says, no, because he is very heavy!!!!!!
