Factual error: When Mr. and Mrs. Stephens are driving in the convertible. In second shot, there are at least 2 tall palm trees along the road. Morning Glory Circle is supposed to be a NY town. There are no palm trees growing in NY. It's obviously shot along a CA road.
Factual error: Benjamin Franklin is portrayed as a gentleman in this episode and the previous My Friend Ben episode. In this episode he dates Aunt Clara at the end. In reality, Benjamin Franklin was a cad, a womanizer and a playboy. He was a marvellous man - a genius - but treated women terribly refusing to marry his common law wife, abandoning her for years while he played with other women in Europe... and treated his daughter like a second class citizen.
