In Gomer's final appearance as a civilian on The Andy Griffith Show (ep. #126, "Back To Nature"), he confessed that he "don't know thang one about pioneerin'." Even Barney Fife's clumsy efforts at living off the land fascinated Gomer. Yet just 6 months later, in this episode, Gomer amazes seasoned Marine vet Carter with literally unbelievable "pioneerin'" skills.
It is said in this episode that Sgt. Carter has been in the Marines 18 years, but in the previous episode, "Officer Candidate Gomer Pyle," he said he had been in for 16 years.
Sgt. Carter's tenure in the Marines continues to fluctuate. In "Officer Candidate Gomer Pyle," he said he'd been in the Marines for 16 years. The next episode, "Old Man Carter" placed him in the Marines for 18 years. In this episode, the officer at the end refers to his 14 years in the Marines.
Corporal Boyle tells Gomer that Sgt. Carter has been arguing with Sgt. Singer for ten years about the difficulty of the job of the Supply Sergeant. Carter later repeats that he's been waiting ten years to prove this point. But Carter only transferred to Camp Henderson midway through Season 1, after being a D.I. for any years, and couldn't possibly have been continuously arguing with Singer for ten years.
When Andy comes to pick up Opie and shakes hands with Sgt. Carter, Gomer remarks how happy he is to see his two favorite people finally meet. But Gomer forgot that Andy and Carter already met on the Andy Griffith show episode where Gomer joins the Marines.
Interestingly enough, the proprietor (James Hong) shows up almost 25 years later in the Chinese restaurant episode of "Seinfeld."
The rock band that appears at the night club where Gomer loses Janice was a band known as The Factory. Two members of that band, guitarist Lowell George and drummer Richie Hayward, would go on to form the critically acclaimed band Little Feat.
Carter tells Duke that someone stole his two back tires, but they were his two driver's side tires.
