The greeting first appeared in Star Wars: A New Hope in 1977, spoken by Alec Guinness as Obi-Wan Kenobi to R2-D2. Ewan McGregor repeated the line in Revenge of the Sith in 2005, dropping in on General Grievous before their duel, and that confident delivery turned it into a widely shared reaction clip. Fans began using the moment for hellos, surprise appearances and mock dramatic entrances across forums, edits and streams, and the phrase has since become one of the most quoted Obi-Wan lines online.
