A man brought a very limp dog into the vet's office. As he laid the dog on the table, Doctor Buck pulled out his stethoscope, placing the receptor on the dog's chest. After a moment or two, the Doc shook his head and sadly said, "I'm sorry, but your dog has passed away."

"What?" screamed the man. "How can you tell? You haven't done any testing on him or anything. I want another opinion!"

With that, Doc turned and left the room. In a few minutes, he returned with a Labrador Retriever. The retriever went right to work, sniffing the poor dog and checking him out thoroughly. After a considerable amount of sniffing, the retriever shook his head sadly and said, "Woof."

The vet then took the retriever out and brought in a cat. The cat walked around the poor dog several times and then sadly shook his head and said, "Meow." Then the cat jumped off the table and left the room.

The vet said, "Well, there's nothing more that I can do." He handed the man a bill for $600. The dog's owner said, "That's ridiculous. $600 just to tell me that my dog has passed on!"

The Doc shook his head, again sadly. "If you had just taken my word for it, then the cost would have been $50, but with the Lab work and the cat scan.... $600!"
