And they were known as Ewoks, right? Someone certainly called them that in the movie, right?
But Actually ...
Now, I have pretty amazing parents, which is why some of my earliest memories involve me watching Star Wars. My whole family casually quoted that movie growing up, and not just the popular quotes ("I thought they smelled bad on the outside," "[incomprehensible Wookie howling]"), but the less recognizable stuff, too ("Threepio! Where could he beeee," "Two cruisers against a star destroyer," "[incomprehensible Salacious Crumb cackling]"). My first toys were Star Wars toys, I had light saber battles with any of the neighborhood kids who wanted to play with me (turns out none of them did) and I'm pretty sure I knew who Boba Fett was before I knew who George Washington was.
I actually still get them confused.
That said, we weren't weird or anything. No one owned a bunch of Extended Universe books, and no one wasted days clicking around Wookieepedia, because the Internet didn't exist. We didn't sit around and watch the credits to learn every character's name and find out who played what.
So how the hell have I known since I was 5 years old that the doofy freaking bears in Return of the Jedi were called Ewoks if that word was never once used in a single Star Wars movie?
