"Haunted"

This Halloween episode (airing on October 29th) is pretty funny, and I like that we get a better sense of the Richie-Joanie sibling dynamic outside the home.  

• Marsha looks blonder now, and she actually has the opening scene with Bag.  Also, Bag writes misspelled profanity, including on Joanie's pumpkin.  (She doesn't know what the word means, but Richie does.)
• I have no idea what the F on Potsie's costume stands for, but presumably not profanity.
• Joanie being in the Chipmunks actually figures into the plot a bit here.
• Three of Garry Marshall's kids (10-year-old Lori, 6-year-old Kathi, and 5-year-old Scotti) show up as trick-or-treaters.
• Garry himself directed the episode.
• Bruce Kelly and David Ketchum co-wrote.  Kelly wouldn't do anything further for the show, but Ketchum not only would write nine more episodes, but he had already appeared as Lt. Col. Binicky in the "R.O.T.C." episode.
