George Lucas -- The Big Tipper

It's obvious George Lucas hasn't gone over to the dark side ... because he left one lucky Jedi waiter a Star Wars-size tip.

The 66-year-old producer/director/mogul and his fam recently went to Manhattan's Serendipity 3 restaurant, ordered up burgers, fries, wings, omelettes and some of their famous frozen hot chocolates totaling $185 ... and then dropped a $100 bill for their server.

The force is definitely with him.
