Haven't caught one of that vendor's commercials in some time, so no clue. However, given it's Oklahoma tv, guessing a family member is often a safe bet.

The Richardson Homes Mom/daughter (assumption on my part) the Watson's couple, Mathis Brother family members, Moore auto group, Ferguson Pontiac commercials, Diffee Ford lads, Joe Cooper Auto, and from days gone by, the little lad and his dad who did Broadway Ford at the entrance to Edmond. I'm certain there are scads of others as well that just are not coming to mind.
