Sport: Boxing.

Event: The Sound and the Fury.

Date and venue: June 28, 1997, at the MGM Grand Garden Arena in Las Vegas.

Memorable moment: Mike Tyson bit off part of Evander Holyfield's ear. Why? Who knows, but maybe it had something to do with the fact that, up until that point, Holyfield was easily defeating Tyson (again). Nobody knows the event as "The Sound and the Fury." It's now called "The Bite Fight." Tyson was obviously disqualified.
