YMMV / Lum and Abner

• Anvilicious: Many of the World War 2 episodes were dedicated to explaining or promoting various wartime programs (rationing, War Bonds, etc). A lot of them were less than subtle about it.
• Life Imitates Art: The town of Waters, Arkansas, on which Lauck and Goff based their fictional town, officially changed its name to Pine Ridge after the show became popular.
• Tear Jerker: Abner's wife leaving him. The episode manages the neat trick of being sad and genuinely funny at the same time. Thankfully, they reunite a few episodes later.
• They Changed It, Now It Sucks!: Starting in 1948, the series tried to mimic the Jack Benny format. This meant adding an orchestra and a live audience, stretching the episodes from 15 mintues to 30 minutes, and making each episode a self-contained story rather than part of a larger arc. Fans weren't too fond of these changes, and, in 1950, the show went on hiatus. It came back in 1953 with the old soap opera format.
