Notadancer
A lady went to a pet shop to buy a parakeet. She asked the clerk for a bird that could sing. The man sold her a parakeet, and she took it home. There, she examined the bird and found out it had a broken leg. She returned to the store with the bird and told the clerk that the bird had a broken leg. "Lady," he answered, "when you brought the bird, you asked for a singer, not a dancer."
