As a standalone soundboard clip, oh great heaven circulates mainly as a short reaction sound rather than as a quoted line from a widely recognised film or show. Its appeal comes from its old-fashioned, theatrical wording, which sounds funnier and more dramatic than a modern wow or no way. Creators reuse it because the phrase is instantly understandable even out of context, and its two-second length fits the fast pacing of short-form video, reaction edits, and meme compilations where a single line has to land immediately.
