​ 6. Super Bowl XLIII

The most-watched Super Bowl in history, with 98.7 million viewers, Super Bowl XLIII pitted the almighty Steelers against the relatively weaksauce Cardinals, who would've liked to clinch their first title since '47. No such luck, as their fourth-quarter surge proved unsuccessful, and Pittsburgh took the trophy 27-23. 

​ 5. Usain Bolt sets world records in Beijing, then breaks them a year later

Jamaican Usain Bolt is stupid fast. His nickname is "Lighting Bolt," for instance. He came away from Beijing with gold medals in the 100m, 200m, and 4x100m relay, and broken world records in the 100m and 200m. That wasn't good enough, though, so he headed to the 2009 World Championships and broke his own records again in both events, just for good measure.

4. Boston Red Sox win the World Series in '04

It was the first championship victory for the Sox since 1918 - cause enough to be excited. But the Sox came back from down 3-0 to the Yankees, their nemesis, in the AL championship series. And then there was Curt Schilling's six innings pitching injured, in which he allowed only one run. And Pedro Martinez's seven no-run innings, and the series-winning home run by Johnny Damon. All around, Boston's domination of the '04 World Series embodied what baseball should be.
