A woman brought a very limp parrot into a Veterinary Clinic.
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 sadly and said, "I'm sorry, but Polly has passed away."
The distressed owner wailed, "Are you sure? I mean you haven't done any testing on him or anything. He might be in a coma or something."

The Vet rolled his eyes, shrugged, turned and left the room.
Returning in a few moments with a beautiful black Labrador. As the bird's owner looked on in surprise,
the dog stood on his hind legs, put his front paws on the examination table and sniffed the parrot from top to bottom.
He then looked at the Vet with sad eyes and shook his head.

The Vet escorted the dog from the room and returned a few moments later with a cat.
The cat jumped up and delicately sniffed the bird. The cat then sat back, shook it's 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. "A HUNDRED AND FIFTY DOLLARS!" she cried. "A HUNDRED AND FIFTY DOLLARS 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... what with the Lab Report and the Cat Scan.....it's $150.00."
