A woman told the vet that something was wrong with her dog. He examined the animal and told her the dog was dead.
"I don't believe you", she said, "I'd like a second opinion"
The vet said that would be fine. He went into the other room and got a cat. He put the cat up on the table with the dog. The cat sniffed the dog and jumped down. The vet then got a black lab, and put him on the table. The lab sniffed the lady's dog and also jumped down.
The vet tells the lady again, "I'm sorry, but your dog is definitely dead. That will be £600 for the examination."
"£600 is ridiculous, what are the charges for?" she exclaimed.
"£50 for me and £550 for the cat scan and lab work."
