Seeing the WOWY video on MTV (back when they played videos!).
U2 shows I've seen
15 - 1 Zoo TV (Detroit), 4 Elevation (Detroit, Chicago-2, Las Vegas), 9 Vertigo (San Jose, Chicago 5/10, Philly, Chicago 9/20, NYC 10/8, Pittsburgh, Detroit 1&2, Cleveland), 1 360 (so far - Chicago 9/12). The best one was when Larry gave me his stick (10/15/01 in Chicago).
Have you met U2?
Have come close, but had many memorable moments during the Vertigo shows that were good enough (for now, lol).
