A few minutes later he returned with a cat. The cat jumped on the table and also delicately sniffed the bird from head to foot. The cat sat back on its haunches, shook its head, meowed softly and strolled out of the room.
The vet looked at the woman and said, “I'm sorry, but as I said, this is most definitely, 100% certifiably, a dead duck.”
The vet turned to his computer terminal, hit a few keys and produced a bill, which he handed to the woman.
The duck's owner, still in shock, took the bill
“$150!” she cried, “$150 just to tell me my duck is dead!”
The vet shrugged, “I'm sorry
If you had just taken my word for it, the bill would have been $20, but with the Lab Report and the Cat Scan, it's now $150.”
