Boba Fett and Darth Maul both have very few lines but are huge favorites. You have to admit, Ric Olie's dialogue is so atrocious it is gag-inducing even if it is only a few lines. And some characters are so cartoony and silly it is distracting to me. But a prime example of a cool character that didn't have much screen time is the one you have for your icon.
