9. "I have a bad feeling about this." - Luke, Han, Leia, C3PO, and others.
Variations of this foreboding expression appear throughout the Star Wars saga. In "A New Hope," Luke says it as the Millennium Falcon approaches the Death Star, and then Han says it just before the walls of the trash compactor begin to close. In "The Empire Strikes Back," Leia says it in the belly of the giant asteroid slug. In "Return of the Jedi," C3PO says it as he enters Jabba's palace, and then Han says it again after the Ewoks capture the Endor strike team. In the prequels, the line is delivered twice by Obi-Wan and once by Anakin.
8. "It's a trap!" - Admiral Ackbar, "Return of the Jedi"
In stating the obvious, Ackbar reveals that he is the last person in the Rebel Alliance to realize that the Empire had set them up. Fortunately, instead of fleeing, the Mon Calimari commander took Lando's advice and ordered his ships to engage the imperial fleet at close range, and, well, you know the rest.
7. "Do. Or do not. There is no try." - Yoda, "The Empire Strikes Back"
A staple of high-school yearbook quotations, Yoda's dictum perfectly captures George Lucas's idiosyncratic blend of Zen Buddhism, Jungian analysis, and sportswear slogans.
6. "Aren't you a little short for a stormtrooper?" - Leia, "A New Hope"
