The line comes from Obi-Wan Kenobi in Star Wars: Episode III – Revenge of the Sith, released in 2005, where Ewan McGregor delivers it as a deliberately casual greeting before facing General Grievous. Clipped from that scene, it spread through prequel meme communities and short-form video, where its polite understatement contrasted with dramatic entrances. It remains popular because the greeting is instantly recognisable even to casual fans, easy to place over any arrival, and funny precisely because it sounds so unbothered.
