Happy Birthday, Iron Mike

Ten years ago, Mike Tyson celebrated his 31st birthday two days early and in the most unusual of ways: by actually biting off a chunk of Evander Holyfield's right ear during a fight.

Nine ears earlier, almost to the day, he had followed a more exciting plan, beating Michael Spinks in a 91 second dismantling that solidified Tyson's standing as the world's undisputed heavyweight champion.
