Here is video of Bill O'Reilly last night where he forgot he was on Live TV as he did a promo for an upcoming segment. He had just finished talking to Monica Crowley and Alan Colmes and was trying to tease a segment on whether President Bush deliberately allowed "Osama bin Laden" to escape from Tora Bora. But he got mixed up and started to say "Obama" instead of "Osama." He caught himself, and then said - "I’m going to have to cut that again."
But he didn't get a do-over, because he was Live.
