Plot
One Friday night while Homer is drunk, he wonders through the woods, and sees and alien. When he gets home, he tells Marge, but she doesn't believe him. Then a local magazine publishes an article on the close encounter, and Mulder & Scully from the FBI go to Springfield to check what's going on.
Even Mulder & Scully don't believe Homer, so to prove them wrong he and Bart camp out in the woods and wait for the alien to arrive, and video tape it.
The next Friday, the whole town returns to the woods to see the alien. When the alien appears, it is revealed to be Mr. Burns, who every Friday night undergoes longevity treatment which leaves him disorientated and confused, with a healthy green glow from radiation.
