The Ropers were OKAY, not great though.
I was a big fan of them, just for the fact that everything was a sexual repressed innuendo with Mrs. Roper haha. Even the most subtle of comments would turn into Helen taking a shot at Stanley and their (lack of) sex life haha.
I don't remember their show much, I don't know if I've seen more than a few episodes, but I loved them on Three's Company, which I've mostly just watched in reruns. I was pretty young when the series ended. I probably watched a little bit of it at the end of it's initial run. It was a show that probably wasn't suitable for someone of the age that I was at that time, but it also really was suitable because really little kids wouldn't get all innuendo's and jokes. I watched a lot of it in the late 80's/early 90's in reruns. Watching it as child and then as an adult was very different. It's much more funnier as an adult, because you understand all the misunderstandings and perveted sexual jokes haha.
I don't remember If I ever watched Three's a Crowd. It flopped and was cancelled after a year. I missed Stanley and Helen when they left, but I also really liked Furley. He was also a complete idiot, which was hilarious. Th episode where Jack plays Jack and his fake twin brother from Texas named Austin, to throw off Furley after he caught him making out with his niece (since he was supposed to be gay to be allowed to live there) was really hilarious. How he kept alternating at both sides of Furley and taking the cowboy hat on and off. And then Janet plays that tape of her and Jack learning some language from the bedroom, while ''Austin'' is out in the living room. Then you hear Cindy's voice in the bedroom on that tape accidentally and Furley's like ''How'd you throw your voice like that?!''. That was one of the funniest episodes of a show that you'll ever see. I recommend everybody watch that episode, even if you never watch another episode of it.
