1989: Shamu completely botches his 4:35 p.m. show
1992: Considered the heavy favorite to win gold in the decathlon, Dan O'Brien fails to even qualify for the Olympics after he forgets his discus, pole vault, and javelin at home
1992: After holding a 32-point lead, the Houston Oilers are just barely able to out-choke the Buffalo Bills
1993: In their only Family Feud appearance together, Michigan's Fab Five lose to the Robertson family because of Chris Webber's boneheaded move to use Jalen Rose's answer "bowl" for "Things You Pack for a Trip"
2008: The New England Patriots fail to win the Super Bowl after going 16-0 in the regular season; let's just take a second to remember how great that was
