The Seattle Times reports that a two-story brick warehouse on Chicago’s West Side is the world capital of fake vomit, where it’s still made the old-fashioned American way, ladle by ladle, formed and coagulated for the next generation of pranksters and troublemakers.

Helping put the ick in America since 1941, Fun Inc. is a repository of practical jokes, magic tricks and gag items — from chattering teeth to hot pepper gum, oversize sunglasses to oversize toothbrushes to oversize anything.

The story explains that in the 1960s, upward of 60,000 fake vomits were produced annually. These days, Fun Inc. brews up the recipe only a few times a year, making around 7,000 latex barfs annually, as tourist gift shops and joke stores look overseas for cheaper versions (though for $15 a dozen wholesale, Fun Inc.’s prank puke is still a heck of a deal).

The story says that fake vomit’s pop-cultural significance earned it a reference on "The Simpsons" during Season 4 in the "Last Exit to Springfield" episode. Nuclear plant owner Mr. Burns shuts off power to the city. When he turns it back on, production at Fake Vomit Inc. resumes. Mechanized fake vomit machine squirts; workers rejoice.

Although fake vomit is immersed deep enough in the pop-culture zeitgeist to warrant its own Wikipedia entry, its ambiguous history exists only in tales passed around factory floors.
