BREMEN, Germany, May 23 (AFP) - Two masked men broke into a bakery here Sunday and made off with a total booty of half a tart, local police said. When the hapless hoodlums burst in and asked for the cash, the woman behind the counter was so nervous she could not open the cash drawer. Foiled in their evil plans, one of the two young men consoled himself with half a tart he snagged from a display.
