Hehe. Try this: Bring down your console while playing SP, and type:
It increases the chances that you'll cut someone's limbs off to like... 100%. My favorite is tossing my lightsaber at a stormtooper. It hits him in the waist, cutting him in half, but because the angle gets all screwy, it proceeds to cut off his head, arms, and legs as well, right before the parts hit the ground. Friggin hilarious.
Give it a shot. Definetly makes the game more interesting, especially when you start cutting Jedi heads off, ala Ep2.
