You have to hand it to them: Fans of The X-Files are a creative bunch. Shortly after the series’ debut on Fox precisely twenty years ago today, they began posting their own fictional stories about the show on newfangled Internet listservs and forums for consumption by other rabid X-Philes. Occasionally, these stories would mix universes, so that Mulder, Scully, and other X-Files characters could hang out with the likes of Anglea Chase, Xena, and George Constanza.

Of course, the actual show wasn’t averse to using this tried-and-true crossover gimmick. Richard Belzer dropped by as John Munch, his Homicide: Life on the Street (and, later, Law & Order: Special Victims Unit) cop, in season five’s “Unusual Suspects.” Vince Gilligan parodied a fellow Fox show with season seven’s “X-Cops.” (A Picket Fences crossover plot almost happened in season two’s “Red Museum,” but CBS scrapped the idea.) And of course there was the 1997 episode of The Simpsons, in which Mulder and Scully determine that an alien haunting Springfield is actually just Mr. Burns.

The influential show may have ended more than a decade ago now, but diehard fans are still cranking out stories. Strangely, about the only series that has yet to receive a fan-fic crossover with The X-Files is Breaking Bad, so Hank-and-Scully shippers will have to scratch that itch some other way. To celebrate the series’ twentieth, here are the twenty most ridiculous crossover episodes that (mercifully) never made their way across Chris Carter’s desk.

Steamiest line: “Mulder didn’t even see the smack coming. The sound of her hand hitting his face was so loud, some of the teams looked up to see if that was gunfire.
