The laugh track comes from the long TV tradition of canned laughter used in comedy and sitcom production, especially across the second half of the 20th century. Online, short laugh track clips became a flexible meme tool because viewers instantly recognize the joke structure they imply. Editors use them to frame a moment as intentionally cheesy, forced, or embarrassingly unfunny. The sound still works well in short-form video because it communicates sarcasm in under three seconds, similar to a buzzer or the classic bruh reaction.
