This thread hasn't had a response in almost a month, meaning this bit of info is probably falling on deaf ears, but I thought I would just pop your proverbial bubble and point this out:

PVP's Scott Kurtz has already released a "Han Shot First" t-shirt. Granted I think the phrase has more meaning when paired with this awesome website's URL but regardless it has been done.
As hostile as it may sound, I vote for the front of the shirt to have a big illustrated hand giving the middle finger accented by the phrase "Fuck your special edition" below it. Childish? Absolutely. Tactless? Of course. Attention grabbing? Without a doubt.
