Yep I remember watching this episode. Mama's in the car and she's like, what's this say?? "Prindle" and Thelma I believe was with her explaining how it all worked lol. It was a good episode.
Actually in 2019 Vicki Lawrence was coming to a towns theater stage that is very local to me. I don't know if the show happened or not because it was scheduled for April 2019, right when COVID was starting to take off.
