Yep yep yep

People vary, so I'm sure out there, somewhere, someone does that.

I read an interview shortly after with the writers I believe. There was a reason behind it. I can't remember more detail at the moment, but at one point, in one of their schemes, Jimmy and Kim had doctored a video to make a wealthy father and son who were trying to get some land look awful for it, the dad was a real cowboy type, at least in his own mind. And it played prominently in the commercial, the dad had a similar drawling way of saying "Yep!" And so having Kim end up with this guy, was a form of punishment and a nod to that.

My take was it was meant to underline how boring her life had become.
