Emergency

Rico says the word showed up on a bus transfer (though Rico's still not sure why) and reminded him of a scene from a movie from his childhood (circa 1966), The Russians Are Coming, in which the crew goes through what's supposed to be Nantucket (but wasn't, except for some short scenes; locations were mostly in California, including Bodega Bay, Fort Bragg, Mendocino, Westport, and Caspar), saying "Emergency! Everyone to get from street!"
