Eight years after Alexander Graham Bell summoned Mr. Watson, someone was already using Mr. Bell's invention to prank their elders. 1884 was the first documented appearance of the prank phone call.
Electrical World magazine ran an article describing how a prankster in Providence, RI, was phoning undertakers "to bring freezers, candlesticks and coffins for persons alleged to be dead. In each case, the denouement was highly farcical, and the reputed corpses are now hunting in a lively matter for that telephonist."
Pranksters continued using the phone for mischief, calling the Bronx Zoo in New York for "Mr. Lyon," the Lincoln Park Zoo in Chicago for "Mr. B.O. Constrictor," and so on.
For decades, April Fools Day became a virtual New York holiday for inflicting these dummy calls on younger siblings and new office workers: on April 1st of 1928, the Bellevue Morgue recorded some 125 calls for Mr. Stiff, 73 calls for Mr. Coffin, and — rather more creatively — another 50 calls for Mr. Biers. The Aquarium was assailed by 2,646 April Fool calls in 1936; the Bronx Zoo got hit with 1,980 calls that same day for the likes of L.E. Fant and Mr. Behr.
Eventually the Bronx Zoo simply took to disconnecting its Wellington 3-5000 number every April 1st, forcing jokesters to resort to Mr. Bush at the New York Botanical Garden and Mr. Snow at the Weather Bureau. The situation was much the same around the country, though Chicago's zoo hit upon a more pugnacious response: phone operators set up a gramophone so that callers asking for Mr. Lyon were promptly hit with an ear-splitting roar through their handsets.
Prank phone calls were still going strong a century later, but Caller ID struck the first death-blow in the 1990s.
Prank phone calls will remain alive as long as people continue to watch The Simpsons.
