The episode: “Jack Frost,” ep. 813
The explanation: Al Lewis was an American character actor best known for his role as Grandpa Munster on “The Munsters.” He looks just like this lady, with his pointy nose and crazy hair. On the show, he was a vaguely vampiric character, another oddball among many in the Munster family. Later in Lewis’ career, he became a political activist and also opened an Italian restaurant in New York, where he often appeared in costume.
Novelty factor: I always enjoyed “Munsters” reruns as a kid, but I didn’t actually know the actor who played Grandpa. I had a good laugh when I realized the comparison they were making.
