Here’s a funny self-defense video from the ‘80s. It’s a karate instructor named Lou Casamassa showing women how to prevent a sexual assault. A few of his tips include grossing out your attacker by drooling on yourself, burping, and passing gas . . . because, quote, “the smell may drive him away.” Then a woman shows how to bite off a guy’s JUNK if you need to. She uses a cucumber instead of the real thing.
