There are so many moments that come to mind, being a wrestling fan since 97-98.
HBK-Austin was one of the first matches I saw, Undertaker's entrance at WM14 also took my breath away.
BUT the match that actually got me into wrestling was HBK-Bret's Ironman match at WM12. HBK's entrance, being a young fan at that time, instantly made him my favorite. The drama behind every move and the storytelling was amazing and to me this match doesn't really get the credit I think it deserves.
