A policeman sent his wife and child to a sea resort for a vacation. After a week he joins them in the hotel. Since he's been away from his wife for a week, he wants to make love with her. "No darling, we can't do it here" she says, "our kid is watching us." "You're right" he says, "let's go to the beach." After a while, they start to make love on an empty beach. All of a sudden, a policeman appears. "Put your clothes on immediately, shame on you, you can't do that in public!" "You're right", said the husband, "but it was a moment of weakness. We didn't see each other for a week. By the way, I'm a policeman too and it would be very embarrassing if you were to fine me." "Don't worry, you're a colleague and it's your first time. But this is the third time I caught her making love on this beach in the last week and she'll have to pay for it!"
