Where and when did this oft heard expression come into popular usage...and why? Why do people inflict this kind of idle harassment on innocent parrots, most of whom would probably rather be called "Reginald", "Steerforth" or "Agatha" or some other name with a little weighty dignity, and most of whom would rather eat something more tasty than a cracker?

Well? Whaddya think?

Could there be a pirate connection?
