This is odd: Yoda looks like a kind of animal, greener version of my former, short, 94-year-old Russian grandfather, Aaron Henry Romanov, (used a different name in America). The pointy ears appear to symbolize how Henry frequently heard "private" conversations. George Lucas had grown up knowing Henry. When I asked him about this, George's answer was, "Yo...(meaning yes)......dah."

(Note: Princess Leia is my Hebrew name -which everyone used for me when I grew up.)
