There are two episodes in particular that, for some reason, made an impression on me that I still remember them vividly. The first is an episode of M.A.S.H. called Dreams where we see the characters having strange and surrealistic nightmares. The other is from, don't laugh, Kate and Allie. The episode is called Fathers and Sons and shows Allie's song, Chip, now grown and revisiting the home that Kate and Allie rented together with their children, that is now being demolished. Chip is with his own son and starts to think about the past, at which we are treated to a fairly atypical episode. At the end the show comes back to Chip and his son leaving the building before the wrecking crew takes down the building. I found the ending disquieting.
Can anyone else think of similarly strange, out of place episodes on an old TV show?
