424. While swallowing the match it gets caught in your throat, you cough it up, and the match hits a domino, which hits a bigger domino, which hits a off balance guitar, which hits a wonkly made wardrobe, which knocks over a massive candle which sets alight to a fuse to a stick of dynamite which blows up a nuclear bomb.
