A cowboy from  Texas  attends a social function where Barack Obama is trying to gather more support for his Health Plan. Once he discovers the cowboy is from President Bush’s home area, he starts to belittle him by talking 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 cowboy says, "Y'all havin' some problem with them circle flies?"

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 replies, "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," 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," the cowboy replies, "I have too much respect for the citizens of this country to call their President a horse's ass."

"That's a good thing," 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."
