A cowboy from Texas attends a social function where Barack Obama is trying to gather support for his Health Plan. As Obama spoke 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 butt?"
"No, sir," the cowboy replies, "I have too much respect for this country to call its president a horse's butt."
"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."
