The poster by Larry's mirror is for the 1969 24 Hours of Le Mans which was the 37th Grand Prix of Endurance, and took place on 14 and 15 June 1969. It was the eighth round of the 1969 World Sportscar Championship season. The other poster is for the 25th anniversary Monaco Grand Prix.
This is the first and only time we get to see Eleanor (Marianne Black), who was Janet and Chrissy's roommate before Jack moved in.
Larry served four years in the United States Marine Corps.
First episode to feature Eleanor's name in the title this is also the last episode to feature her name
