A woman brought a very limp parrot into the Veterinarian's office. 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, 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 just be in a coma or something?"

The Vet rolled his eyes, shrugged, turned and left the room returning a few moments later with a beautiful black Labrador dog.

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 the dead parrot from top to bottom. He then looked at the Vet with his sad, brown eyes and shook his head. The Vet patted the dog and took it out of the office, but returned a few moments later with a cat!

The cat jumped up and also sniffed delicately at the bird. 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."
