A woman takes a very sick, lame duck to the vet, they lay the duck down on the top and the vet examines it. After about 5 mins of prodding, poking and listening with a stethoscope the vet says "I'm sorry your duck has passed away Madame."
"Are you really sure ?" she said, "is there nothing else we can do, I'm not so sure it is dead."
Reluctantly the vet says " Ok " and leaves the room, he comes back in with a Black Labrador, the dog puts his paws up on the top has a sniff and licks the duck then sits down on his haunches and looks at the vet, "Ok" says the vet and leaves the room with the Labrador.
He comes back in with a cat, the cat jumps up on the top has a good sniff round the duck, gives it a lick, jumps back down and sits down on it's haunches and looks at the vet.
" Ok " says the vet I really am sorry but your duck really is dead. "Alright" says the woman "how much is the bill ?" "£1500 " says the vet, "that's a bit steep !" says the woman.
The vet says " well it would have been £50 but after the Lab report and the Cat scan the costs goes up"
