A woman brought a very limp duck into a veterinary surgeon. As she laid her pet on the table, the vet pulled out his stethoscope and listened to the bird's chest. After a moment or two, the vet shook his head and sadly said, "I'm sorry, your duck, Cuddles, has passed away."
The distressed woman wailed, "Are you sure?"
"Yes, I am sure. Your duck is dead," replied the vet.
"How can you be so sure?" she protested. "I mean you haven't done any testing on him or anything. He might just be in a coma or something."
