Joke

So a cop pulls me over the other day and while he's writing out my ticket I see that he keep having to swat at a mosquito.
So I goes to him "Circle fly bothering you?'
He says "It's a moquito"
So I say "nope. I know a circle fly when I sees one" .
"What's a circle fly?" he asked.
I say " well we me and my brother used to have horses we'd notice all day long they had to swish thier tale at the circle flys that gather on thier bums"
He looks at me and says "are you calling me horses behind?"
SO I look and say "Oh dear no officer. But you can't fool them cirlce flys."
