A woman takes her unresponsive pet duck to the vet. The vet checks for a heartbeat but finds none. Vet: "I'am sorry ma'am, but your duck is dead"
Woman: "That can't be! Maybe he's in a coma or something? I insist you do further test!"
The vet leaves the room for a minute, then comes back in with a black labrador. The dog sniffs and tries to wake up the duck to no avail then looks at the vet with sad eyes and shakes his head and leaves the room.
Vet: "See ma'am, like I said, your duck is dead"
Woman: "I refuse to believe you! It's imposible - there must be something you can do? my duck can't be dead!"
They vet again leaves the room and returns a minute later with a cat. He places the cat on the exam table and it sniffs the duck from head to toe. With sad eyes and a low sad groan, the cat looks at the vet and shakes his head and leaves the room. The woman, now convinced and upset as the vet types away on his computer and prints out a bill and hands it to the woman. She looks at the bill in shock.
Woman: "$150 dollars! You want $150 dollars for telling me my duck is dead!"
Vet: "Well ma'am, normally it would be $20 dollar, but with the Lab test and the "Cat scan, I had to charge more"
