Circulated online as a short soundboard clip, the Zelduh laugh is best known simply as an old man's laugh, rather than as a line tied to a widely documented scene. That vagueness has helped it travel, because creators can drop it into almost any context where a sly, knowing chuckle fits without needing the audience to recognise a specific show or game. Its under-a-second length also makes it easy to reuse in memes, edits and reaction clips, where a quick audio cue can carry the joke.
