This remix of Bush’s speech from the September 30 debate reminds of the story about the guy who made a tape of the between-word sounds he made while giving a lecture. He edited out all the speech and kept only the umms and uhhs. There was twenty minutes of it! Voke, a Finnish teacher I had in high school, used to tell this story to make students pay attention to the stalling sounds we make when speaking publicly.
Here’s another work of edited footage, this one video from the Republican National Convention.
