A woman brought a duck to the veterinary hospital. The vet pulled out his stethoscope and listened to the bird's chest.
After a moment or two, he shook his head and said "I'm sorry, your duck is dead."
" How can you be so sure?" she asked. "You haven't done any testing on him." He may be in a coma."
The vet rolled his eyes and walked out of the room. He returned with a black Labrador Retriever.
The woman watched in amazement as the dog stood on his hind legs, paws on the examination table, and sniffed the duck from top to bottom.
With sad eyes, the dog looked at the vet and shook his head.
Leaving with the Retriever, The vet returned to the room with a cat. The cat jumps up on the table and sniffs the duck from head to foot, looks at the vet and shakes its head.
The vet looked at the woman and tells her, "I'm sorry, but I'm sure your duck is dead."
The woman was outraged when she received the bill. "$150.00!" You're charging me $150 dollars to tell me my duck is dead?"
The vet shrugged. "I'm sorry." "If you would have taken my word for it, the bill would have been $20, but with the Lab report and cat scan, it's now $150.00"
