My favorite Wrestlemania moment isn't necessarily a moment that's mentioned, but it is during the Rock-Hogan match at Wrestlemania X8 when Hogan "hulked up" for the first time in a WWF ring in almost 10 years.

Everything about the moment. The initial Rock Bottom. The kick out, followed by the insane crowd reaction once they all realize what's going on. Lawler throughout the entire clip just marking the FUCK out, JR keeping his cool until his legendary "Oh my God..." and then the excited JR "He beat Andre the Giant with that move!!!" the crowd reaction to all the emotion and theatrics that Hogan and Rock, two of the best showmen in the history of the business, were showing them. That is a moment that will continue to give me chills every single time I see it.
How about you guys?
