First: “Get Smart”, the first two seasons.
Second: “Laugh In”, the first two seasons.
Third: “SNL”, the first two seasons sans certain overboard bits.
Honorable Mention: “The Tonight Show”, from Steve Allen through Jay Leno. That is an incredible run of a pretty funny, cool show.
Just an observation, very few shows mentioned are from recent years.
I don’t know if Free Republic people skew older, or whatever age, just don’t like today’s TV shows that much, but most of shows mentioned are from decades ago.
Personally, I do skew a bit older, just turned 60. And also don’t watch much current TV because so much of TV today is pushing the liberal agenda. Also, in my opinion, many shows today just don’t seem as well written or intelligently written as the shows of yesteryear.
