A man took his lifeless dog to a veterinarian who pronounced it dead.  Unable to accept the death of his dog, the man asked for a second opinion.

The vet called in his pet Labrador, who sniffed around the lifeless dog and then announced that it was indeed dead.  Still not satisfied, the man asked for a third opinion.  This time the vet had his cat examine the man’s dog.  It, too, signaled that the dog was dead.  The man left broken-hearted, but was back in a week complaining about the vet’s $500.00 bill.

“Well,” said the veterinarian, “That's $200 for the consultation, $150 for the lab report and another $150 for the cat scan.”
