hmm, I'm going to limit my list to the ones that I actually saw live as they mean a lot more to me than like, the immaculate reception and other classics that were before my time.
5. Super Bowl XLII (2008, Patriots fans Q.Q after a perfect season gets ended by the Giants in the superbowl. As much as I hate the giants, I'm glad that no one has to deal with insufferable Pats fans having a perfect season to brag about)
4. 5th Overtime of game 4 of 2000 NHL Easter Conference Semi-Finals (Flyers vs. Penguins. I remember staying up until like 3:30 AM watching this game in 8th grade. Phenomenal hockey, Keith Primeau's goal in the 5th OT was the icing on the cake).
3. Overtime of game 1 of the 2001 NBA Finals (76ers vs. LAL, after getting completely molested by Tyronn Lue and some Refs who wouldn't know a foul if it punched them in the face, Allen Iverson caught fire and completely lit up the much better Laker's team to prevent their perfect post season run)
2. 9th Inning of the 2001 World Series (Arizona vs. NYY, Arizona's batting pulls 2 runs off the previously unhittable Mariano Rivera to win the World Series.)
1. "World Champions... World... ****ing... Champions!" (Chase Utley, Phillies 2008 Word Series victory parade)
