In The Dark Knight from 2008, Michael Caine's Alfred Pennyworth says the line to Bruce Wayne while explaining why the Joker cannot be reasoned with or bought. The speech became one of the film's most quoted moments, circulating first as a movie quote and later as a short audio clip in edits, memes, and reaction videos. Its appeal lies in how calmly it frames pure chaos, making it useful far beyond Batman stories. Creators still use it whenever a character, plan, or situation turns destructive for no clear reason.
