(Episode opens at a shot of Lakeside's skyline at precisely 12:00 A.M., on October 31)
The Narrator: Ah, midnight in Lakeside - where any restaurant imaginable is still open, and where men look at dubious sites on the Internet.
(Dark, large fog suddenly appears, and it covers the whole city)
The Narrator: (coughs) Gah! It smells bad! (coughs) What's going on?!
(Satan appears holding a pitchfork)
Satan: (laughs) Halloween is always my favorite day! (to the audience while putting on a party hat) And it's also my birthday. (advances towards the camera) SO TELL ME HAPPY BIRTHDAY, OR ELSE!
(Please Stand By)
Satan: Soon, some important friends and I will make this our town, and eventually, OUR WORLD! (laughs)
Man: (offscreen) I'm trying to SLEEP over here!
