Man, I wish I had one of those shirts. That's something. I did keep my diploma and "Now I Get It" pens for the same reason.
....oh, and the "you jackass" look my wife gave me after the whole thing came crashing down is seered into my eyeballs as a momento of the whole thing.
(Actually, she was far better about the whole thing. "Live and learn" and "oh well" were more the looks.) We did take a couple extra days for Atlanta and saw Bill Murray in the Atlanta airport so it was all worth it.
