In a tale by Leonard Nimoy, Homer drinks too much at Moe's Tavern and opts to walk home late one night. He hears something strange and encounters an eerie glowing creature with bulbous eyes and a contorted body emerging from the woods. At home, disheveled and shaken, he wakes up Marge, but the entire family passes off Homer's sighting as a product of his drinking.

The next day, the Springfield Shopper prints a story about Homer's UFO encounter. The story finds its way to the Washington bureau of the FBI, where it is read by "X-Files" agents Scully and Mulder. Mulder convinces his skeptical partner to investigate the sighting further. They travel to Springfield to interview Homer and visit the sight. Finding Homer's credibility shaky and the people of Springfield annoying, they quickly leave.

Bart and Homer set up camp at the site and videotape the alien during a return visit. The following Friday, hundreds of Sprinfielders gather to glimpse the alien. Wneh the creature finally appears, Lisa shines her flashlight on it, revealing its true identity. The being is actually Mr. Burns, who has been receiving appearance-altering longetivity treatments from Dr. Riviera.
