Apologies if this has appeared before but I couldn’t find it via a search.
A woman brought a very limp parrot into a veterinary hospital. As she lay 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 sadly and said, "I'm so sorry, Polly has passed
The distressed owner wailed, "Are you sure? I mean, you haven't done any testing on him or anything. He might just be in a coma or something."
The vet rolled his eyes, shrugged, turned and left the room returning a few moments later with beautiful black Labrador. As the bird's owner looked on in amazement, the dog stood on his hind legs, put his front paws on the examination table and sniffed at the parrot. He then looked at the vet with sad eyes and shook his head.
The vet led the dog out but returned a few moments later with a cat. The cat jumped up and also sniffed delicately at the ex-bird several times methodically from top to bottom . The cat sat back, shook its head, meowed and ran out of the room. The vet looked at the woman and said, "I'm sorry; but like I said, your parrot is most definitely, 100% certifiably ...dead."
He then turned to his computer terminal, hit a few keys and produced a bill which he handed to the woman. The parrot's owner, still in shock, took the bill. "$150!" she cried. "$150 just to tell me my bird is dead?!"
The vet shrugged. "If you'd taken my word for it, the bill would only have been $20, but with the Lab Report and the Cat Scan, what did you expect?"
