The line comes from Joker, the 2019 film starring Joaquin Phoenix as Arthur Fleck, a failed comedian who adopts the Joker persona. The polite greeting stands out because it is delivered by a character audiences already associate with chaos and violence, which gives an otherwise ordinary phrase a dark second meaning. After the film's release, the clip was lifted into short sound libraries and meme edits, where its brevity made it easy to reuse. It remains popular because it instantly signals a villainous entrance without needing any explanation.
