The episode Appointment in 8-B made me think of Three's Company because Ralph Misunderstood when he walked by that lady door and thought it was George Jeffersons and not a different George and Louise thought he was having a affair but George did not know why she was mad and he did not have a affair and Louise thought George was leaving her. anyway it reminded me of Three's Compant because it was a whole Misunderstanding which is what Three's company is known for and The Jeffersons and Three's Company have the same Producers and Writers.
