A woman took her pet duck to the vet. The duck just didn't look right and wasn't moving. The vet put the duck on the exam table and listened to its heart. And he said, "I'm sorry mam, your ducks dead." The woman said, "No, no, he can't be dead. He's looked like this before. He's just not feeling well. Are there anymore tests that you can do? I'm just sure he's not dead." The doctor thinks for a minute and tells her that there were a couple of tests that he could do. So he calls in his dog. The dog jumped up on the table and sniffed the duck then he looked up at the vet and shook his head. Then the vet brought in his cat. The cat jumped up on the table and sniffed the duck and shook his head no as well. The vet explained to the woman that he was sorry for her loss, but both the dog and cat confirmed that the duck was dead. The woman accepted that the duck must infact be dead asked the doc, "what do I owe?" The vetrinarian replied "$150". Dismayed the woman exclaimed "150 dollars! you're going to charge me 150 dollars just to tell me that my duck is dead!" To this the doctor replied, "Well, if you'd have taken my word for it this would have only cost you $20, but with the lab test and the cat scan, it's $150."
