Ironically, when I bought a box of “The Twilight Zone” trading cards (1st one of 4), I got both the Shatner - “Nightmare at 20,000 Feet” card and a Bill Mumy card.
Mumy was scary as hell in his episode but a nice guy in person (unless you piss him off and gives you that finger).
I also enjoyed the one about the spinster living with her uncle, an inventor who was always tormenting her because they didn’t like each other.
But she was his heir and put up with it, and waited on him hand-and-foot.
He dies, so she thinks she’s in clover and starts living the life with her inheritance: fancy clothes, restaurants, etc.
Little did she know that he had built a robot in the basement that was his mechanical replica. She goes back to being a drudge—for the robot.
“Bar-ba-ra! Bar-ba-ra!”
