YES! YES! The little brat (Me) finally did it! If I see Movie Maker again today, it'll be too soon.

This is the Prisoners of Gravity episode "Fans". From the episode guide:
471002 FANS AIRDATE: OCTOBER 8, 1992
Walter Koenig (Chekov) and Michael Dorn (Worf) bring a Star Trek perspective to this week's show as SF authors Douglas Adams (The Hitch Hiker's Guide to the Galaxy), Lois McMaster Bujold (Barrayar), Spider Robinson (Time Travelers Strictly Cash) and comic book creators Dave Gibbons (Watchmen), Garth Ennis (Hellblazer) and Neil Gaiman (Sandman) provide the anecdotes, and Julius Schwartz and Forrest J. Ackerman explore the history, as Commander Rick examines the phenomenon of fandom. Harlan Ellison (The Essential Ellison) is his usual acerbic self as he enlightens Rick on the dark side of fandom.
