"While fighting their way through the Crimson Jihad camp, Harry (Arnold Schwarzenegger) hands Helen (Jamie Lee Curtis) a MAC-10 he took off a terrorist. In one of the film's more humorous scenes, Helen drops the weapon down a flight of stairs causing it to go off when it hits each step, the stray rounds scoring several kills. This scene was re-created on Mythbusters and thoroughly debunked. "
