I agree. Just a joke that only a few would get. I love the state of Oklahoma and visit it whenever I can.
The last time I was in Ardmore I had a view camera taking pictures of the sunrise over the county court house for a post card company, I photographed almost all the county courthouses in OK for them either at sunrise or sunset. There are many beautiful courthouses in Oklahoma but many were torn down and replaced by buildings with absolutely no personality.
The difference between pigs and people is that when they tell you you're cured it isn't a good thing.
