Just be gracious and admit you were wrong. You said Al was not awarded an Oscar when in fact he was. As I stated previously, Hollywood is all about double standards.

Notice in 2006 he is not listed. The fact that he went up on stage is beside the point. As for double standards, we were talking about the Memorial segment not honoring people who are not really involved with the film industry. It has no bearing on who is the subject of a given film. If Al Gore died he would also probably not be part of the Memorial segment.
