An American tourist in London found himself needing to go to the bathroom something terrible. After a long search he just 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 go."
"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 urinating 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," retorted the policeman. "It's the French Embassy."
