A cowboy from Texas attended a social function where Barack Obama was trying to gather support for his re-election.?? When Obama discovered the cowboy was from President Bush's home area, he started 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 a$$?"

"No, sir," the cowboy replies, "I have too much respect for the citizens of this country to call their president a horse's a$$."

"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."
