This is a really bad one and hope it has not been sent before.

A man took his parrot to the vet saying that it wasn't very well. The vet examined it and pronounced it deceased. The owner wasn't satisfied and asked for a second opinion.

The vet called in his cat who scratched the parrot and confirmed the diagnosis. The owner still wasn't satisfied and called for a third opinion.

The vet called in his Labrador who sniffed the parrot and confirmed the opinion of the others. The owner at last pronounced himself satisfied whereupon the vet presented him with a bill for £150.

The man protested at the amount of the bill but the vet told him that the bill was perfectly reasonable - after all the parrot had had a cat scan and a lab report.
