A man was walking home from work late one night. As he strolled down the sidewalk, he heard a womans voice say from some nearby bushes, "20 dollars?"
Without thinking twice, the man lept into the bushes and starting having sex with the mysterious voice.
Moments later, a police officer was walking by and heard the comotion. Shining his light he said, "Hey!", "You there in the bushes, what do you think you're doing?!"
The man replied, "Do you mind?", "I'm trying to make love to my wife!"
The officer apologized saying, "Sir, I didn't realize it was your wife."
The man replied, "Neither did I til you shined that damn light over here!"
