A Republican cowboy from Texas attends a social function where Hillary Clinton is attending, and trying to gather more support for her nomination. Once she discovers the cowboy is a Republican, she starts to belittle him by talking in a southern drawl and single syllable words.
As she was doing that, she kept swatting at some flies that were buzzing around her head. The cowboy says, "Y'all havin' some problem with them circle flies?"
She stopped talking and said, "Well yes, if that's what they're called.
But I've never heard of circle flies."
"Well ma'am," 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," Hillary replies as she goes back to rambling. But, a moment later she stops and bluntly asks, "Are you calling me a horse's ass?"
"No, ma'am," the cowboy replies, "I have too much respect for citizens of New York to call their Senator a horse's ass."
"That's a good thing," she responds and begins rambling on once more.
After a long pause, the cowboy, in his Texas drawl says, "Hard to fool them flies though."
