Tony Stark first appeared in Marvel Comics in 1963 and became a global film icon when Robert Downey Jr. played him in Iron Man in 2008, the film that launched the Marvel Cinematic Universe. Stark's quick, sarcastic lines were widely clipped from trailers, interviews and movie scenes as the franchise grew through The Avengers and later films. Short voice bites like this one circulate on soundboards and in fan edits because the character is instantly recognisable, even without any picture or context on screen.
