Colin Male, who plays the Game Warden, is also the announcer who opens every episode with, "The Andy Griffith Show, starring Andy Griffith."
Howard Morris, who plays the part of George, the TV Repairman, is best known on the show for playing the part of Ernest T. Bass.
Goober does a crude impersonation of Cary Grant's "Judy! Judy! Judy!" in this episode. He also did the same impersonation in the season 4 episode, "Fun Girls".
Right in the beginning, after Barney convinces Andy and Helen to spend the day together, Andy wonders how he can thank Barney. Barney says "Make me your best man." Fast forward to 1968, in the beginning of Mayberry RFD, and Barney IS the best man at Andy and Helen's wedding.
This is the first time Goober uses his personal comic refrain, "Say it again", whenever another character is talking about a subject that Goober doesn't understand. His cousin, Gomer, whom he replaced in the series, had his own catchphrase, "Shazam", for whenever he encountered something astonishing.
