Shocked at how funny it still is
I caught two episodes recently just to see how much I would cringe and I was surprised at how funny and entertaining they were.
I realized that the humor was based on over the top, cartoonish behavior and the liberal preachiness was balanced with just enough self-deprecating hypocrisy to provide that eye rolling laughter. It's as if the cast was wise enough not to be overly serious. If anything the whacky 70's look actually helped the comedy over the years rather than make it look dated. It was a very pleasant surprise. I'm going to see if I can record more episodes on TV Land.
