According to the mailbox in front of Fred Rutherford's house, his "estate" had the name of "Rancho Rutherford".
Ward's 1957 Ford Fairlane 500 2-door is shown for the first time.
When Beaver goes upstairs to talk to Wally, Wally is seen reading a California State Series Literature Reader by Leroy E. Armstrong, called "Seventh Year" (Sacramento: California State Board of Education/California State Printing Department, 1916).
As Fred is leaving the Cleavers' house, he says that Wally is "kind of small for 15, isn't he?" Ward replies that Wally is 13. Then Fred says, "You know, both of my boys were offered scholarships, football scholarships." However, the only Rutherford son ever seen throughout the series is Clarence ("Lumpy"), who is basically Wally's contemporary.
In earlier and later episodes, the Cleavermobile is a four-door Ford vehicle. In this episode, it's a two door model. In the later seasons, the vehicles switch to a Plymouth name plate
