Wanda Holloway - A Texas Cheerleader Mom's Murder Plot
January 31, 1991 - Channelview, Texas
It's not unusual for parents to do whatever it takes to see their kids succeed, but Wanda Holloway took it to a new level in 1991 when she was arrested for hiring a hit man to kill the mother of her daughter's cheerleading rival.
The intended target was Verna Heath, mother of Amber Heath. Police say Holloway's theory was that if Amber's mother was killed, the student would be too distraught to try out for cheerleader, making it easier for Holloway's daughter Shanna to land a spot on the squad.
Holloway turned to her former brother-in-law for help arranging the plot, who played along with the plan just enough to help the sheriff's department catch her before anyone got hurt.
Holloway, who was later nicknamed "the pom pom mom," was arrested and charged with solicitation of capital murder.
Despite being convicted, her first trial was overturned. She pleaded no contest and ended up serving six months of a 10-year sentence.

Mike Tyson vs. Evander Holyfield - The Bite Fight
June 28, 1997 - Las Vegas, Nevada
Billed as "The Sound and the Fury," the bout between Mike Tyson and Evander Holyfield may be considered one of the most shocking moments in sports - especially because a chunk of one fighter's ear ended up in the ring.
During the second round of this match, Holyfield headbutted Tyson, leaving him with a cut above his right eye. Tyson complained about headbutting the first time they fought. However, referee Mills Lane ruled this incident accidental.
In what Tyson said was retaliation for the headbutting, he bit Holyfield's right ear in the third round. The fight continued and Tyson bit Holyfield again, this time on the left ear.
Tyson was disqualified, had his boxing license revoked and was fined $3,000,000. Some speculate Tyson was trying to get out of the fight.
His boxing license was reinstated about 18 months later.

Renault was charged with conspiracy and denied the accusations of cheating. However, in an about-face, Renault chose not to contest the allegations as two top officials quit and bans on the team were put in place.
