This happened to an Englishman in France who was totally drunk.
A French policeman stopped his car and asked the gentleman if he has been drinking.
With great difficulty, the Englishman admitted that he has been drinking all day, that his daughter married a French man, and that he drank champagne, a few bottles of wine at the reception, and quite a few glasses of single malt thereafter.
Quite upset, the policeman proceeded to alcotese (breath test) him and asked the Englishman if he knew why, under French law, he had just been arrested.
The Englishman answered with humor, "No! Do you know that this is a British car and that my wife is the driver... on the other side?"
