Not a dancer

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.”
