The line comes from Friday, the 1995 American buddy comedy directed by F. Gary Gray and starring Ice Cube and Chris Tucker, a film whose everyday neighbourhood dialogue became endlessly quotable online. Short excerpts circulated first as ringtones and soundboard clips, then in reaction edits and short videos where a single scolding line could sum up disbelief. This exchange survived because it needs no setup, the question sets a scene in seconds and the water remark works as a standalone joke, so new viewers understand it even without seeing the film.
