I wrote a paper on chewbacca once in UG. I forget what the topic of the paper was. I think my topic was something like "Barthes and the Chewbacca Principle". It was on some sci-fi dime novel that my prof was obsessesed with that was trash with a cyborg or something (he was really obsessed with gender and cyborgs are neuter, which he thought was interesting, noone else did though).
