Larry the African Grey Parrot dials an imaginary phone number, rambles a little, then starts laughing.
Wikipedia says: “Dr. Irene Pepperberg’s research with captive African greys, most notably with a bird named Alex, has scientifically demonstrated that they possess the ability to associate simple human words with meanings, and to intelligently apply the abstract concepts of shape, colour, number, zero-sense, etc. According to Pepperberg and other ornithologists[who?], they perform many cognitive tasks at the level of dolphins, chimpanzees, and even a human toddler.”
