The prank of chaining the rear axle of a car to a stationary object, with the same outcome Lumpy's car experiences, was later used in the movie American Graffiti (1973). Tony Dow (Wally) and Frank Bank (Lumpy) often claimed that the producers of American Graffiti (1973) stole the idea from this episode. George Lucas eventually admitted to them that he had not stolen, but borrowed, the idea.
The house from which Wally and Eddie make the prank phone call to Lumpy is the same house as Cindy Andrews's from Eddie's Sweater (1963).
The Rutherfords are apparently now living in the house formerly occupied by Penny Woods's family. When Beaver stops by Penny's house in Beaver's Doll Buggy (1961), he and Penny are seen in front of the garage, with a stone wall behind Penny. Later, Penny's mother comes out onto the front porch to ask if the kids want refreshments. Here, Wally and Eddie are seen in front of the same garage and stone wall, working on Lumpy's car and Fred comes out onto the same front porch to check on their progress.
This is the last "Leave It to Beaver (1957)" episode to air as a network program. Originally aired in May, 1963, it was broadcast on ABC as a rerun at 8:30 PM on September 12, 1963. A week later, the new 1963-64 television season got underway. "My Three Sons (1960)", starting its fourth season, took over the 8:30 PM time slot and "Beaver" moved into perpetual syndication.
When Lumpy pulls up in his car at the end of the episode, the car's model emblem is visible just forward of the door. But when Eddie and Wally walk up to the car moments later, the emblem is gone.
