Really, I'm not THAT Crazy....Right?

Well, it's official. My husband and everyone around me think I'm crazy. I need your help to prove otherwise!!! Remember back in the day when the classics like Punky Brewster, Alf, and The Jettsons used to be on after school? Or maybe it wasn't after school for you but I remember it was for me. Either way, that's neither here nor there. My problem is I remember really getting into this one show and for the life of me I can't remember its name. It involved a family with a robot who was a maid/sister. She wore a red dress with a white lacy apron over it and her back would open up and she was in fact, robot. She had all these wires and lights and everything going on in her back! Everyone suspected she was a robot but it was the big family secret and they were able to convince people she wasn't somehow. The logistics are lost on me and my failing memory. And then there was the nosey, robust neighbor that was constantly saying "no-no-no-no-no-no!" all the time. Ringing any bells??? My husband is convinced it's a Mainer thing, and all the others that I've asked look at me like I have three heads and ask if it was The Jettsons. Really...I'm NOT crazy. There was a show like this...someone HAS to remember!! What was it called?!?!?!?!
