To help you better understand Ziggy and his pain tolerance:
A few years back he was sitting in a relatively large lecture hall (a rare occurrence, as attending class is unusual for Ziggy; he learns most things a few hours, or even minutes, before exams and still manages a solid GPA), the professor made eye contact with him, maintaining it for an uncomfortably long period of time. This made Ziggy a bit uneasy, so, to break the tension, he punched himself in the face. hard. He then casually got up and left class. His eye was black, blue and swollen shut the next day.
Also, fist fights are relatively common, though not usually his fault, including one that he needed stitches in his eyebrow and lip for, but, rather than waste time at the hospital, he just went to bed. The next morning he attended brunch at the school's main dining hall still wearing the blood drenched shirt from the night before - his wounds still open and damp. When the dining hall worker told him to get cleaned up before he could come in, he just turned his shirt inside out (it was white, so it made no difference) and sauntered right in. It was brilliant.
Last but not least (and these anecdotes are by no means exhaustive), Ziggy once ran full speed into a deck railing without jumping (on purpose)... thereby catapulting himself over the railing, doing a complete somersault, and landing flat on his back on the frozen ground. If you have the imaginative capacity to picture this, it's really quite remarkable. After lying incapacitated and gasping to breathe for a few minutes, he got up and resumed drinking.
Despite many of the poster's compulsion to downplay this feat or even its validity, Ziggy is no joke. Although I've since grown up and have not had the pleasure of witnessing this, I simply wanted to point out that an endeavor like this requires a multitude of unique qualities. Ziggy has those.
