Train Your Abs at Home - an article that details the content of the "Iron Abs in 8 Minutes" video.
In general, this old TV show clip presents a workout method that effectively trains the muscles of the middle and upper abs. If you haven't trained using this method before, your abdominal muscles will start burning after just 1-2 minutes of the program.
The author himself trained using this program, and the results of his workouts are visible in the photos in the article "Defined Abs - Preparing for Summer". It's more fun to train with friends, and doing so will make your workouts more effective.
