Lightning doesn’t strike twice

“Lightning doesn’t strike twice” means that a rare event doesn’t usually happen twice. If something really lucky or unlucky happens, it is unlikely to happen again. In the episode, movie sequels are almost never better than the original, because “lightning doesn’t strike twice,” or you can’t get that lucky more than once. If you get in a car accident and are nervous to drive again, someone might try to reassure you that “lightning doesn’t strike twice,” or that you are unlikely to get in another car accident.
