The line comes from William Friedkin's The Exorcist (1973), spoken by Father Damien Karras, played by Jason Miller, as he and Father Merrin arrive at the MacNeil house to confront the possessed Regan. Delivered with gallows humor before the film's terrifying climax, it became one of horror cinema's most quoted one-liners. Decades later it resurfaced as a soundboard and meme staple, especially around Halloween, sitting comfortably alongside other movie quote soundboards like Darth Vader's famous scream and horror-game clips such as the Phasmophobia ghost attack.
