I'm very glad many have mentioned Savage and Miss Elizabeth reuniting at WrestleMania. After a fantastic match between the Warrior and Savage the ending was just tear-jerking. So that is one of the all time great moments in history, it played so perfect.
Chris Jericho's E debut was one of my happiest moments... the countdown, the anticipation, the pyros, the drawn out moments of darkness until the name JERICHO light up the TitanTron. Still makes me smile.
Edge defeating Cena at NYR. Even though i dont think it played out as dramatic as it should have been. It was great to still be shocked in this day in time. I still dont like Vince McMahon coming out and spoiling the surprise by saying Edge was turning in Money in the Bank... Then Edge's music and entrance. Wrongly, Vince didnt have faith in the fans, that they would understand what was happening.
Lastly at WCW uncensored 1997, when Sting finally choose sides. Repelling down into the ring after the NWO had just won the Main Event.... and single-handedly took out Hall, Nash, Savage and Hogan. It was 6 months in the making at that point, and i remember losing faith that Sting would show up that night... making it a very happy moment.
