In 1985, Douglas Adams made the media rounds to promote his then-new novel So Long and Thanks for All the Fish. Part of the promotional tour found him making an appearance on Late Night with David Letterman. You can experience the awkward television magic that resulted by watching the video featured here. The most interesting part of this is how Letterman remarks "good luck with the film" at the end of the segment. At the time, Adams was working with Ivan Reitman on a movie version of The Hitchhiker's Guide to the Galaxy. We all know how that turned out.
Anyway, I'll have the contest up for you shortly.
