Boxer Mike Tyson was such a bulldog in the ring that many of his foes would literally shake in their boots at the thought of being hit by this guy. When Mike lost his compass (in the form of his long-term manager and friend), the boxer also seemed to have lost his mind. His tales of woe are very well known and subject enough for the record books. Lately, Iron Mike has made quite a resurgence in career and persona, appearing in a number of television shows and movies as a kinder, gentler Mike Tyson. –mark anderson
