A cowboy from Texas attends a social function where President Obama is trying to gather support for his largely unpopular socialist policies. Once he discovers the cowboy is from President Bush's home town he starts to belittle him by talking down to him in a southern drawl and single syllable words.
As he was doing that, he kept swatting at some flies that were buzzing around his head. The Texan says, "Y'all havin' some problem with them circle flies Mr. President?"
President Obama stopped talking and said, "Well, yes, if that's what they're called, but I've never heard of circle flies."
"Well, sir," the cowboy replied, "Circle flies hang around ranches. They're called circle flies because they're almost always found circling around the back end of a horse."
"Oh," President Obama replies as he goes back to rambling. But, a moment later he stops and bluntly asks, "Are you calling me a horse's ass?"
"No, sir, Mr. President" the Texan replies, "I have far too much respect for the citizens of my country to call our President a horse's ass."
"That's a good thing," President Obama responds and begins rambling on once more.
After a long pause, the cowboy, in his best Texas drawl says,
"Hard to fool them flies, though, Sir."
