When Andy makes a more serious warning to the farmers later, they reveal that they had run off a deputy earlier.
Knowing that they're talking about Barney, Andy makes up a story about "Crazy Gun Barney" and "that dirty game he plays" and how his running off was just a ploy.
When referring to his personality quirks (not wearing a hat after someone, etc.) he would always say, "my mother was the same way." And, it never fails that when his name is in print, it's always misspelled as either Fice or Fike, resulting in comedic frustration.
Barney is also extremely over-dramatic when it comes to his duties.
Though constantly warned by Andy, Barney falls for countless scams.
This gullibility is evident in many episodes, including, Barney's First Car where he is conned into buying a lemon from a crafty old widow.
All them things I said; for example, his using the squad car for personal reasons. As far as Andy knowing his job, I'd just like for you to take a look in the record book, Mr. You know there ain't been a major crime committed in this town thanks to Sheriff Taylor? Sometimes considered a blowhard with delusions of grandeur, Barney fancies himself an expert on firearms, women, singing and just about any other topic of conversation brought up while he is around.Despite his shortcomings, Barney is zealous about law enforcement, regularly spouting off penal codes and ordinances to thugs and jaywalkers alike.An emotional powder-keg, Barney often overreacts with panic, despair or bug-eyed fear.After numerous misfires (usually a Colt or Smith & Wesson M&P .38 caliber revolver), Andy restricts Barney to carrying only a single bullet in his shirt pocket, "in case of an emergency." However, the bullet always seems to find its way back into the pistol where, predictably, it is accidentally discharged.The accidental discharge of Barney's pistol becomes a running gag: Barney gives a lecture on gun safety and either shoots the floor through his holster, or assuming the safety latch is on, causes the gun to fire.
