My favorite E3 moment (bookmark) is Paul McCartney and Ringo Starr appearing to promote The Beatles Rock Band and it being obvious they had nothing to say about it and they being honest about having nothing to say about it, basically just appearing on stage, saying "game is good" and leaving. Second only to Yoko Ono and Olivia Harrison appearing just to wave at the audience a couple minutes earlier
Truly the apex of celebrity guest appearances
