This was definitely one of the weakest episodes. It was also very strange because it was one of only 2 I know of not to feature Sgt. Carter. It was probably the most "realistic" episode too, which proves being "realistic" is not all that valuable. It made sense that Gomer would go and visit Frankie, seeing as both his parents were dead and he had no siblings. I wonder though, was Schell not available that week? It would have made for sense for Pyle to have visited him...
