I officially hate this brain bug. When you pick up a baseball bat, do you accidentally whap yourself with it? HELL no! Swords are even easier to swing than a baseball bat, and the gorram lightsabers most of all.
Quote me this, please. Every source I've seen (And I is a big ole warsie), says they have a standard power source for the setting, not 'teh infinat power'
