I love hearing those! Post up some of the best zingers you've heard, @Hoov, please! Last really good one I heard was at Academy in Yukon; (I like to go there and just listen).
"I only carry a Glock, cause everything else can fail" - (Youngish employee still poopin' high school chow standing behind the gun counter adamantly explaining why this old guy needed to buy a Glock 17 for his similarly aged wife). Wife looked like she didn't want to be there.
In Oklahoma, if it is Open Carry, it is specified it must be in a holster (or scabbard, etc.) designed for such. Can't just tuck it into your belt and go all Open Carry in the Kroger. Of course, you can conceal it in your pocket with your car keys, cig lighter, etc., without a holster.
