MASH
Dick Van Dyke
The Avengers, still clever
What amazes me about those last four is that there was no way of taping those shows and some episodes I only saw once but all it takes is one trigger to get the memory banks rolling. I would have been a better student of history and other memory based courses if I'd had teachers that looked like Mary Tyler Moore or Diana Rigg.
I own MASH but will only start a re-watch from the laugh track dumped seasons, I cannot stand laugh tracks and that's why I don't re-visit DVD or Cheers.
I never watched The Office or Parks and Recreation the first time around and recently went through all the episodes of each and liked them a lot. I am on Community now and that's a great watch at night when I don't want to think and just be served stupid with a moral. But, I seldom get through one without a laugh.
