So I found the secret T-shirt giver. I emailed the Homestar Runner store asking who the person was that made the order and gave them the tracking number. I didn't think they would reply since I received the order without any trouble so their part of the deal was done. Anyways, not a secret admirer like some people thought, ha ha, just some appreciation for my computer skills. Anyways, since I made a big deal about the mystery, I feel obligated to bring it to a conclusion. So thank you, Cynthia Hershberger, for the shirt. My other one was getting old so now I have a fresh one!
