Leia: Jangotroopers tend to be exactly two meters tall - I mean, they ARE clones, after all. You seem to be a few centimeters shorter than that - are you really a Jangotrooper?
Luke: What are you talking about, m'lady? Oh! Are you referring to my Jangotrooper armor? I can see why it would be confusing. Fear not, m'lady! [Luke removes his helmet and shakes loose his long curly shoulder-length tresses] See? No clone under this white armor! My name is Luke Skywalker, and I came to the Death Star with several other freedom fighters in order to rescue you.
