The line comes from the 2003 independent drama The Room, written, directed by and starring Tommy Wiseau as Johnny. In the scene Johnny angrily denies hitting Lisa, saying he did not do it before a rooftop outburst that became one of the film's most quoted moments. As The Room gained a cult following through midnight screenings and online clips, Wiseau's unusual delivery turned the denial into a standalone meme. It is still used whenever an unconvincing denial needs a dramatic, instantly recognisable punchline.
