One night in Paris, an American tourist dropped into a sidewalk cafe late one night and, after a couple of drinks, realised he was the last person in the cafe except for a chap sleeping at one of the tables.

The man called the proprietor over and asked for his bill.

"Would monsieur care for another drink?" asked the Frenchman.

"No thanks, I imagine you want to close up. Why don't you send that other fellow home?"

"Well, I should," said the other. Then, with Gallic logic, he added, "But each time I wake him up he asks for the bill and pays it again."
