Are You Kidding is best understood as a short-form reaction sound rather than a clip tied to one famous scene. Its appeal comes from its brevity and tone: in just over a second, the repeated laugh signals disbelief without needing dialogue or context, so editors can drop it into almost any surprising moment. That flexibility has kept it in regular use across meme edits, reaction videos, and comedy shorts, where a quick, sarcastic response works better than a longer explanation. It survives because the feeling it captures, amused disbelief, is endlessly reusable.
