UPDATE: No wonder Thompson's paying attention to the Internet: "As of Wednesday afternoon, Thompson’s video, in which he suggests that Moore might look into a mental institution, drew 598,600 viewers on Vimeo, YouTube and Google Video. That dwarfs the most views from any moment during the debate."
It was easier, too. It probably took a half hour or less to make that video. People sometimes say that Thompson's lazy, but I'm put in mind of the Robert Heinlein short story, The Man Who Was Too Lazy to Fail.
