A lady went to a pet shop. "I'd like to buy two yellow canaries," she told the owner.
"We don't have any canaries, but we have these," the owner said, as he showed the lady some pale green parakeets.
"That's not what I'm looking for," the lady stated.
But the pet storeowner refused to give up. He said, "Just think of them as yellow canaries that aren't quite ripe yet."
