Glenn took his dog to the veterinary clinic, and laid its limp body on the table. The doctor pulled out his stethoscope, listened to the dog's chest for a moment, then shook his head sadly. "I'm sorry, but your dog has passed away."

"What?" Glenn screamed. "You haven't even done any tests! I want another opinion."

The vet left the room and returned in a few moments with a Labrador Retriever. The Retriever sniffed the dog on the table carefully from head to toe. Finally, the Retriever shook it's head and barked once (meaning "dead and gone").
