A man's walking late at
night when he sees a woman in the
shadows.
"Twenty bucks,"
she says.
He's never been with a
hooker before, so he decides what the
hell. They're going at it
for a minute when all of a sudden a
light flashes on them---it's
a police officer.
"What's going on here,
people?" asks the officer.
"I'm making love to my
wife," he answers indignantly.
"Oh, I'm sorry, I
didn't know," says the cop.
"Well, neither did I
until you shined that light in her face."
