The 'Here's Johnny' meme originates from Stanley Kubrick's 1980 psychological horror film, The Shining. In the scene, a crazed Jack Torrance, played by Jack Nicholson, uses an axe to break through a bathroom door to reach his terrified wife, Wendy. Nicholson improvised the iconic line 'Here's Johnny!', referencing the introduction from The Tonight Show Starring Johnny Carson. On the internet, this template is used to represent an unwanted or startling intrusion, whether it’s a person, an object, or a realization suddenly appearing in an aggressive or comical way. It remains one of the most recognizable frames in cinema history, perfectly capturing the essence of being 'cornered' by something inescapable.
