An American tourist in London was desperate to take a leak. After a long search he couldn't find any public bathroom to relieve himself. So he went down one of the side streets to take care of business. Just as he was unzipping, a London police officer showed up.
"Look here, old chap, what are you doing?" the officer asked.
"I'm sorry," the American replied, "but I really gotta take a leak."
"You can't do that here," the officer told him. "Look, follow me."
The police officer led him to a beautiful garden with lots of grass, pretty flowers, and manicured hedges. "Here," said the policeman, "whiz away."
The American tourist shrugged, turned, unzipped, and started pissing on the flowers. "Ahhh," he said in relief. Then turning toward the officer, he said, "This is very nice of you. Is this British courtesy?"
"No," replied the policeman. "It's the French Embassy."
