The mocking laugh belongs to Nelson Muntz, the school bully from the animated television series The Simpsons. Nelson is voiced by Nancy Cartwright, and his sharply delivered “Ha-ha” became one of the character’s defining catchphrases during the show’s long run. Clips of the laugh later circulated widely in reaction videos, meme edits, soundboards, and gaming content. It remains useful because audiences can recognize both the character and the intended joke within seconds: someone has suffered a foolish, awkward, or deserved setback.
