A friend of mine from high school bragged that he achieved some measure of infamy in middle school by hacking Diablo in such a manner that it was possible to duplicate items. He then claimed Blizzard offered him an internship -- again, in high school -- for showing them how he did it. I knew about the incident (oh, the wages of a misspent youth -- Diablo, not hacking), but always figured he was embellishing most of it.
Some years later, sure enough, guess who was in the Diablo II credits.
