I think a commenter here beat him to that joke, by the way.
He finally watched the video of Ahmad's "clock invention."
The point of this is that word is going to get out. Maher plays the video in his show.
Sure, you can read that blog piece about how trivial an act of "invention" this was, but seeing is believing. That video is powerful.
The media can't play this video for the same reason it can't play the Planned Parenthood videos they claim "simply don't exist."
