From a tipster (but edited)…
CNN took the feed early and I was flipping through the channels and stopped because I thought the speach was starting early and it was strange really no other way to describe it…he was looking all serious…he looked like he was frozen in the middle of saying a word…or completing a thought…just strange
From DailyKos…
Jeff Greenfield was babbling about something, and the picture cut to George. First speaking, and then looking at the camera with a very confused expression. Stuck there for several seconds, then cut back to CNN’s studio. Blitzer then talked for 45 seconds straight trying to explain what had just happened.
From Wonkette which was liveblogging the event…
7::59 PM: HA, we just got a five-second clip of the president saying stuff we weren’t supposed to hear. Apparently the president was “rehearsing,” and the network pool picked it up inadvertently. (Rehearsing? Didn’t know he did that — could have fooled us.)
Drudge has a cap…

Now who will be the first to post the video?
UPDATE: YouTube has the video…
