Barack Obama flew to London to meet Gordon Brown. Halfway through the motorcade along the streets of the English capital, Obama leaned over to Brown and whispered: "I desperately need a pee." "No problem," said Brown who immediately relayed instructions in the driver's ear. Seconds later, the car drew to a halt outside an impressive building and Brown led Obama inside. The interior of the building featured a huge marble hall with an ornate fountain and beautiful tapestries hanging on the walls. "Where is the toilet?" asked Obama. "Just go right here," advised Brown. So Obama unzipped himself and peed all over the marble floor, and Brown did likewise. Then both men washed their hands in the fountain before drying them on the tapestries. "This is a magnificent place," said Obama. "What do we do now?" "Anything you like," replied Brown. "It's the French Embassy."
