Since we have a thread on what Simpsons episodes you would want inducted in the National Film Registry if they ever allow TV show episodes for preservation, I thought I would start a thread for episodes of other TV show that you think deserve the same status.

I think the series premier episode of "All in the Family" titled "Meet the Bunkers" deserves preservation due to it being so groundbreaking. Also the episode "Gloria and the Riddle" would be a great choice as well due to how meaningful it is.
