Dick was good-so was Tow Snyder-and Mike Douglass-Dick blows Charlie Rose out the water.....

Wow - Everybody - there is no such thing as true logic in any of the Douglass Adams works. At one point in his story, the protagonist learns to fly. The trick is simple as explained by the book: When you're falling, you just need to forget to hit the ground.
So johnald is wrong - everything in this video is simply made up for a good humoring story.

After reading the book and the whole HHG series some 4 or 5 times now, I really enjoyed listening to the audio books of the HHG series read by douglass adams. What a treat to hear him tell the stories.
