I love Bingowings' idea!
Sam has made more than 100 movies http://www.imdb.com/name/nm0000168/ , so I'm pretty sure there's some dialog that can be used.
Obviously, it's too time consuming to watch all them, so it would be easier to just go to Sam's IMDB profile and click on his character names and check out the "Quotes" section.
(Windu's quotes, for example, http://www.imdb.com/character/ch0000003/quotes )
