Mama..We just watched one of maybe my top 3-4 episodes of The Waltons..

"The Firestorm". When John Boy upsets everyone by insisting on warning the people of Walton's Mountain about the Nazi intentions by publishing parts of Hitler's book, Mein Kampf in the Walton's Mountain newspaper. I think it's maybe Richard Thomas' best work on The Waltons. The ending is pretty intense.
