I recently saw an interview with Valerie Harper, who said one of her very first TV acting jobs was on "Mayberry RFD." She said she only had a couple of lines in the episode. I don't see this listed on IMDB or from any other source. She said she got the part on the show because she and Arlene Golonka were roommates when they were starting out. Does anyone know what episode Valerie appeared in?

That's interesting, I never knew that. But I haven't seen Mayberry RFD in years. Also interesting, Golonka appeared on TMTMS, with Valerie again!

Maybe she was uncredited in the episode. I don't remember her in any but I haven't seen the show since TNT reran it years ago.
