Video: Lightsabers are dangerous as hell. If I had access to one in this here real life, I'd be legless, armless, headless, and torsoless in less than 5 minutes. Not even kidding. Even people who know how to use lightsabers get their body parts laser chopped off. Check out this compilation of all the amputations in Star Wars from Pablo Fernandez Eyre, many done by lightsabers.
Poor C-3PO, always losing his parts.
