S08E10 The Springfield Files
In yet another crazed crossover, Leonard Nimoy narrates another tale of the supernatural, reminiscent of his days with "In Search Of." Realizing that even he's too drunk to drive after a night at Moe's Tavern, Homer stumbles through the woods and encounters a green glowing alien. Needless to say, nobody takes him seriously, except for "X-Files" FBI Agent Fox Mulder, who once again drags along his partner Dana Scully on another quest to prove the government is hiding the presence of UFO's from the public. However, even this mission may make a skeptic out of Mulder.
