Check out this YouTube clip of David Attenborough with a lyrebird. Out of all his myriad onscreen moments, the UK audience voted this one the favourite, and no wonder. The lyrebird is a superb mimic of natural and artificial sounds, and this one generously treats David to a portion of his repertoire, making kookaburra sounds, camera sounds, car alarm sounds, chainsaw sounds… stunning stuff.
The clip reminds me of a joke I read in Isaac Asimov‘s Treasury of Humor (one of over 500 books he wrote or edited):
A stranger came into a bar in which there were only the bartender, a dog, and a cat.
As the stranger ordered his drink, the dog rose, yawned, and said, “Well, so long, Joe,” and walked out.
The stranger’s jaw dropped. He said to the bartender, “Did you hear that? The dog talked.”
“Don’t be a jackass,” said the bartender. “A dog can’t talk.”
“But I heard him.”
“You just think you heard him. I tell you dogs can’t talk. It’s just that wise-guy cat over there. He’s a ventriloquist.”
