 Zoo Removes Parrots from Display After Birds Keep Cursing at Visitors

There's an anecdote that I recall from the 1930's - the midst of the Great Depression.   A Congressman was paying a visit to the National Zoo in DC, when he happened to pass by a myna bird.  As he did, the bird called out to him, "How about an appropriation?"  "That's impertinent!" the Congressman exclaimed.  "So's your old man," the bird is said to have replied.

Never underestimate the trouble that a talking bird can get into.  Although, to be honest, the zoo did get that appropriation.
