A woman brings a duck to the Veterinarian. Vet says, Your duck is dead. Woman says, Are you sure? Yes, says Veterinarian. How can you be sure, you’ve done no tests. Vet brings in a Labrador Retriever which sniffs the duck and shakes his head. Next, a cat which sniffs the bird and shakes its head. Vet says, Sorry, but as I said your duck is dead. Vet hands the woman a bill. She cries, $820 to tell me my duck is dead! Vet says, If you had taken my word for it the bill would be $20, but Lab Reports and Cat Scans cost extra!
