I was a kid when this show originally aired and it was one of my favorites. They sometimes rerun them on NIck or TVLand, but it’s nice to see them up online as well. Thanks for asking the question.
If you are ever in Washington, DC, be sure to visit the International Spy Museum. It is really well done (when I went, some got dragged along for the ride, but walked out REALLY having had a great time). LINK
It is a fun interactive museum and puts in context what the show was spoofing and even has an exhibit on the show as well. Going through it will give you even more of an appreciation of the show.
Did you see and like the remake?
