Ladies and gentlemen, this is Chewbacca. Chewbacca is a Wookiee from the planet Kashyyyk. But Chewbacca lives on the planet Endor. Now think about it; that does not make sense! Why would a Wookiee, an 8-foot-tall Wookiee, want to live on Endor, with a bunch of 2-foot-tall Ewoks? That does not make sense! If Chewbacca lives on Endor, you must acquit! The defense rests.
It’s in the script ... that’s why. :-P
Maybe Chewie likes it dwarfey style.
Ewok females make good spinners for Chewie ?
