No reliable source work, character or year is attached to this clip, and the phrase itself appears to be the whole joke rather than a quote from a known scene. It circulates as a user uploaded soundboard reaction, shared for its brevity and randomness rather than any story behind it. Because it is only about a second long, creators can insert it anywhere a normal reaction would feel too predictable. That lack of context is why it keeps being reused as a deliberately baffling punchline.
