Three that haven’t yet been mentioned:
1. A criminal (Cory?) is sentenced to solitary on a deserted planet. Every so often a space ship brings him supplies. One trip, they bring him a female robot. He hates her at first, but eventually comes to love her and she “loves” him.
Finally, the ship comes one day and says that the prisoner has been pardoned. They will take him back to earth, but there is no room for the female robot so they shoot her.
I think Ted Baxter (or was it Ted Knight) played in this episode.
2. Several characters, a clown, a soldier, a ballerina, ... are trapped in a giant cylinder with no doors and no windows. Every so often, they hear a ringing from outside. Finally, one climbs out only to be thrown back in.
Turns out it’s a can with little toy dolls inside. It’s Christmas and the Salvation Army is ringing a bell and collecting the toys.
3. One of my least favorites is with Billy Mumy who plays Anthony, a child (monster) who has supernatural powers - he turns one guy into a jack-in-the-box. Cloris Leachman was in this episode.
