Listen close and you can hear the faint beat of a human heart in Eddie Haskell.
In this episode, Beaver mentions that he'd had his tonsils removed when he was younger. However, in the Season 4 episode "Beaver's Tonsils," he still has them.
While watching this episode, I noticed that the scene of Downtown Mayfiield was actually a scene of Downtown Skokie IL. circa 1959. I have a pictorial history book of Skokie with the same picture looking north on Lincoln Ave circa 1946. I recorded it on my DVR and stopped the picture. I could see the same buildings especially the First National Bank of Skokie which was built in 1907. I even saw the same 20 MPH speed limit sign in both pictures.
