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.
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.
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.
