Star Wars

This morning, Myla and Luke were playing Star Wars while I got dressed for work.  Keep in mind that they've never seen Star Wars--most of what they know they've picked up from friends at school.  This is what I overhear:

Myla:  I'm Princess Leia, so you are Luke Skywalker.
Luke:  I want to be Princess Rapunzel.
Myla:  There is no Rapunzel in Star Wars.  You can be Luke Skywalker, or Obi-Wan-Kenobi.
Luke:  I be Luke Skywalker.
Myla:  That's good, because I'm Princess Leia, and Luke Skywalker is her brother, and you're my brother in real life.

Then they play with their "life savers" (light sabers) for a while, and I hear:

Luke:  I'm bigger than you!
Myla:  No, you're not.  Princess Leia is older.  Right Mom?
Me:  Umm, I think Luke and Leia are twins?  I'm not sure?  (As Matthew reads this, he considers filing for divorce.)
Myla:  Mom says they're twins, so neither is bigger.
Luke:  Then I be Darth Vader!
Myla:  Darth Vader is bad.  But maybe you can be Anakin Skywalker.  Is he bad, Mom?
Me:  Well, he becomes Darth Vader when he grows up (spoiler alert), but before that, he's pretty good, I guess.

Et cetera.  I can't believe how much they know about this stuff.  I need to get my hands on the Cliffs Notes or something!
