The Addams Family began as Charles Addams cartoons in The New Yorker in 1938, before becoming a television series in 1964 with a theme by Vic Mizzy. The finger snaps were written into the music and quickly became the family's signature sound, instantly signalling their cheerfully macabre world. Later films and animated versions kept the same musical idea, and the short clip now circulates online as shorthand for anything spooky, eccentric or darkly comic.
