(Andy & Barney are outside Sheldon's hotel room - they've realized he's a thief)
Barney: You know, Andy, it's a shame about these fellas that steal.
Andy: Yeah, they ought not to do that.
Barney: I was reading an article about 'em in one of the police magazines. "Kleptamineracs" they call 'em.
Andy: What's a "Kleptaminerac"?
Barney: It's a person that steals cause he can't help it.
(Barney is mis-pronouncing "Kleptomaniac")
This is the first time we see Barney swear in extra deputies. Throughout the show most of the supporting characters like Floyd, Gomer, Otis, and Goober would be sworn in for one reason or another. It was also common for Barney to line all of them up military style.
This was the last appearance of Dick Elliot as Mayor Pike. He had passed away about two months before this episode aired.
