A woman takes her dead parrot into a vet's office... And lays it upon the examination table. The vet takes one look at the deceased bird and says, 'Sorry Ma'am, but your parrot is dead.' The woman isn't satisfied, and asks for a second opinion. The vet obliges and pokes his head into the next room and calls in a second doctor. A cat saunters in, jumps up onto the table, looks up to the vet with sorrow in his eyes and says, 'Meow.' 'Sorry,' the vet says, 'my colleague says your parrot is dead. The woman still isn't satisfied and wants yet another opinion. The vet, as before, pokes his head into the next room, but this time a dog bounds in, puts its paws on the table, sniffs the bird and barks. 'Sorry Ma'am, but that's three doctor's opinions. Your bird is certainly dead.' 'Alright,' the woman says, 'you win, here's the $50 for the appointment.' '$50?' The vet exclaims, 'You owe me $150 for the extra cat scan and the lab report.'
