The line comes from Stanley Kubrick's 1980 horror film The Shining, adapted from Stephen King's novel. Jack Nicholson's character Jack Torrance chops through a bathroom door with an axe to reach his wife Wendy, then leans in and delivers the phrase as a twisted take on Ed McMahon's nightly introduction for Johnny Carson on The Tonight Show. The scene became one of horror's most quoted moments, endlessly parodied in television, comedy and memes, and the audio alone now signals a manic surprise entrance.
