I heard about this before. I think it's cool that Peter Norvig puts it in his CV: "1998 Television writer: Code written by me for my first textbook was shown on the TV show The Net on 10 Oct. 1998. I was uncredited for this work" (<a href="http://www.norvig.com/resume.html" rel="nofollow">http://www.norvig.com/resume.html</a>)
