circle flies

[Blooddrive]

Ole Bubba the Redneck got pulled over by a State Trooper for speeding. The trooper started to lecture Bubba about his speeding, and in general began to throw his weight around to try to make Bubba feel uncomfortable.
Finally, the trooper got around to writing out the ticket. As he was doing that, he kept swatting at some flies that were buzzing around his head.
Bubba said, "Having some problem with them Circle flies there, are ya?"
The trooper stopped writing the ticket and said, "Well yeah, if that's what they are. I never heard of Circle flies."
So Bubba says, "Well, circle flies are common on ranches. See, they're called circle flies because they're almost always found circling around the back end of a horse."
The trooper says, "Oh," and goes back to writing the ticket. Then after a minute, he stops and says, "Are you trying to call me a horse's butt?"
Bubba says, "Oh no, Trooper. I have too much respect for law enforcement to even think about calling you a horse's butt."
The trooper says, "Well that's a good thing," and goes back to writing the ticket.
After a long pause, Bubba says, "Hard to fool them flies though."
