Kate Micucci appears as a guest star in an episode in season 4 called 'Check Mate' as a waitress. She then later plays the part of Joy and Eddie's daughter, Ally Stark (one of the four different actresses that play Ally Stark.)
The school where Eddie and Jeff teach is loosely based on Josh Goldsmith's alma mater Cheltenham High School, where one of the history teachers is Charles Stamm. There is no vice principal named Mr. Woodcock at this time, there is however another history teacher named Mr. Woodcock who has a British accent.
The exterior of the Stark's house was also used as the Kravitz's house in "Bewitched." In the pilot you can see the Stevens' house in the background across the street. The Stark's house exterior was also used for the Partridge family home and was remodeled after that show ended. The house used for the exterior shots for the Woodcock's home was also used as Tony Nelson's in "I dream of Jeannie"
