There is no widely documented original scene behind this clip, which is part of its charm as an internet sound: the joke does not depend on a specific film moment. Instead, it belongs to the online tradition of taking a familiar Star Wars villain and dropping him into a completely unrelated, everyday comparison. Short meme sounds like this travel easily between edits, reaction videos and social posts because the premise is instantly understood. The contrast between Vader's dark reputation and a hippo's goofy bulk keeps it reusable whenever a creator wants a fast, unexpected laugh.
