At least he didn't have a Hindenburg moment. The Springfield Files sees the arrival of Mulder and Scully to Springfield, where they investigate claims of an alien out in the woods at night. However, the "alien" turns out to have a simple explanation: it's actually Mr. Burns, illuminated from years of working in a nuclear factory, and disoriented after medical treatments designed to keep him young - or at least alive. Wait, maybe that's not such a simple explanation after all. In any case, it's not the first time Homer has claimed to see a UFO. At least this time he wasn't soaked in booze.
