R2-D2 has it good. Despite the occasional foray into battle, the little droid does pretty well for himself. He gets carted around in spaceships, has a big gold buddy and is down with a princess. However, like all droids, every once in a while he needs a tune up. As in an oil change. Little did we all know, but R2-D2 runs on delicious soy sauce.
