The Monkees' address number has been changed from 1334 N. Beechwood to 1438 N. Beechwood.
On the day after this episode appeared, The Monkees' second album More of the Monkees was released.
This episode originally ended with an attractive woman handing Peter a note at yet another testimonial dinner, injecting more impending trouble for The Monkees.
Davy's song and dance number "Old Folks At Home" is a repeat performance from Episode 5, "The Spy Who Came In From The Cool,'' in Episode 45, "The Monkees In Texas" and Episode 54, "The Monkees In Paris."
The exterior and interior set used in The Remington Clinic in "The Case Of The Missing Monkee" was reused as a police station in Episode 25, "Alias Micky Dolenz." It's front steps was used as the City Hall front enterance in Episode 36, "Monkee Mayor."
In the scene where Mike, Davy and Peter confront Dr. Marcovich and Bruno at the operating table, Mike snatches up a menu and reads, "My patient!" On the menu is the name "Vincent Van Gogh Gogh," which is the same name as the discotheque in Episode 4, "Your Friendly Neighborhood Kidnappers."
The brief Asian-sounding musical dirge first heard in this episode during the scene in which Micky, Mike and Davy take a policeman to a French restaurant to find Peter is reused in Episode 21, "The Prince And The Paupers" No. 24, "Monkess A La Mode, and No.26 "Monkee Chow Mein."
Right after production wrapped on this episode, The Monkees put filming on hiatus to take a crash course rehersal for their live concert, which occured in Hawaii at the Honolulu International Center Arena on December 3, 1966.
Mike's hair can be seen parted on the left and Davy and Micky's on the right in one shot, probably ude to a reversed film interpositive.
The wording of the note changes between the readings by Peter and Mike.
Two popular TV series are referenced in this episode. Micky does a hilarious take on Batman when he calls for the Bathook! whilst Peter renders a cue from Act I of Ben Casey. Trivia footnote on Ben Casey: pre-Monkees Davy Jones appeared (with pre-Batgirl Yvonne Craig) as a glue sniffing, wife beater in a December 27, 1965 episode of the series entitled, "if You Play Your Cards Right, You Too Can Be A Loser."
At one point in this episode, Mike makes a reference to TV Guide. Nearly 4 weeks later, The Monkees would be featured on the front cover of TV Guide's Jan.28-Feb. 3 1967 issue; the first of two appearances on the magazine.
