Sexual Inuendo

A Belgian couple was making love in their car parked along the side of the road.

A policeman knocks on the window. The man opens it, and the policeman says,

"Bon jour, monsieur. What are you doing here?"

"I'm making love."

"That's illegal here... That will be a 200 (Belgian) franc fine."

At this point, his ladyfriend appears.

"What's going on, cheri?"

"Oh! Since there are two of you, the fine will be 400 francs!"
