Noted in the "table sauce" aisle at Reasor's...
...Billy Sims Barbecue Sauce and Selmon Brothers Barbecue Sauce.
But these Sooner greats aren't just to be found in the stores. Heisman Trophy winner Billy Sims has a barbecue place at the Farm Shopping Center now, where the dishes are named after the opponents of the Sooners -- e.g., the beef brisket plate is the Bevo Plate. And Outland Award winner Lee Roy Selmon (youngest brother of Lucious and Dewey) has a couple of theme restaurants in the Tampa area, where he played pro football.
In the course of "researching" this story, I came across this funny Oklahoma retelling of Hansel and Gretel -- "Harold Dean and Grettie Mae." You'll find four more Okie fairy tales linked from this page. They made me laugh so hard my wife figured out I wasn't working and told me to do some chores. Darn it.
