Good week for: Emergency pit stops, after a Japanese car-accessory firm unveiled a new portable toilet designed for use in the back seat of a car. The portable commode “will come in handy during major disasters such as earthquakes,” said a company spokesman, adding, “or when you’re caught in a traffic jam.”

Bad week for: Philanthropy, with the news that Paris Hilton is headed for the blighted African nation of Rwanda to film a reality TV show about celebrities doing good works. The hotel heiress admits she is “really scared” about the five days she will spend saving Rwanda.
