If you're a nerd like me you may have seen a version of the t-shirt (to my knowledge originally created by the webcomic Diesel Sweeties) that reads "Chewie Is My Co-Pilot", a riff on the frequently seen "Jesus Is My Co-Pilot" bumper sticker. If you have no idea what I'm talking about, check this out:
I think the Chewbacca shirt is really funny (you can buy it here, btw.*) but what I find most interesting about it is that in Mexican culture, "Chuy" (pronounced "Chewie") is often used as a nickname for the name Jesus (pronounced "Hey-Seuss"). So in Mexican and Mexican-American culture Chewie=Jesus. So even though the "Chewie Is My Co-Pilot" shirt is meant to be nerdy, irreverent, and even a tiny bit blasphemous, in a weird, round-about way it could be interpreted as saying the exact same thing as the thing it is making fun of. Given Diesel Sweeties' apparent political leanings, I don't think this is intentional. It's just a funny little coincidence.
What's not a coincidence however, but a cold hard fact, is that the popular "Han Shot First" nerd shirt is a very thinly veiled proclamation of creator Scott Kurtz's belief that "the Jews are responsible for all wars."
* - UPDATE: Just kidding, you can't actually buy he shirt anymore because Lucasfilm is a bunch of douche nozzles.
