Let There Be Light
I was sitting at a bar and asked the bartender where I could find a prostitute.
He told me to go to the back door, down the dark alley and give the woman there 20 bucks.
So I go outside and hand a 20 to the woman there and started getting busy. After a few minutes, a cop walks past and shines a flashlight on us and says 'What the hell are you doing?'
I said 'Having sex with my wife.' He said 'I'm sorry, I didn't realize that was your wife.'
and I said, 'Neither did I till you shined a light on her.'
