a man woke up one day and his dog wasn't moving. he took it to a vet and the vet said "your dog is dead".
the man said i want a second opinion, and a third.
the vet said fine. he left and came back leading a labrador retriever. the dog sniffed the other dog and went "woof woof". the vet led him out and returned with a cat. the cat sniffed the dog and went "meow meow". the vet led him off and came back. he said that will be $500.
the man says "what! $500 to tell me my dog is dead?"
the vet says "well my fee is only $20. the rest is for the cat scan and the lab report"
