Remember the TV show "Green Acres"? Each appliance had a number on it and Lisa couldn't plug in anything more than "7". Same concept, different characters.
Really?! I sure do remember that show. When they first moved to the farm, and the electric company was installing the meter, she kept telling the POCO guy that they a bigger "electricical" (pronounced, "ee-lec-tri'-si-cle"). I guess she was right! I never noticed that part of it.
