Richard Dawkins dedicated The God Delusion to Douglas Adams, author of The Hitchhiker’s Guide to the Galaxy. Adams introduced Dawkins to Lalla Ward, the former actress to whom Dawkins is now married. Adams and Ward knew each other from working together at Doctor Who, where Adams was a script editor and writer and Ward was the magic princess of the planet Atrios and the second incarnation of Time Lord Romana.
Adams also co-wrote a sketch for Monty Python’s Flying Circus (episode 42, A Party Political Broadcast on Behalf of the Liberal Party.) Go forth and impress others with your grasp of trivia.
For extra credit, Ward was briefly married to Doctor Who number four Tom Baker, hence Doctor Who and Dawkins are spiritually connected three different ways.
