Mulder and Scully crash a high school's 20th reunion dance in Kansas as part of a fraud
investigation. One of the attendees, a weatherman harbouring an unrequited love, is the
Rain King of the title as his emotions are affecting the weather.
From Mania <http://www.mania.com/columns/amhh/amhh120498.html>:
A romantic comedy, with stormy overtones. Weatherman Holman Hardt (David Mannis) has
had a crush on Sheila Fontaine (Saturday Night Live's Jackson) for over twenty years, and
his repressed feelings are causing some very strange weather! Watch for a shot of a cow
crashing through the roof of Mulder's hotel room at the Cool View Motor Court, and for
Mulder to crash a disco-filled high school reunion.
An online chat with Vince Gilligan describes this story, writer Jeffrey Bell's first
contribution, as "extremely funny and sweet story much in the vein of (Darin)
Morgan".
