The recipe for a revolutionary new hangover neutralising treatment has been left in cab by a technician on his way home from a party thrown in honour of the breakthrough. The formula, believed to instantly remedy all effects associated with heavy drinking the night before, has not been found. Gareth Prong, the man charged with looking after the briefcase containing the one and only piece of paper on which the formula was written before its inventor died prematurely from acute sclerosis of the liver, was unavailable for comment this morning. Reporters camped outside his North London house were surprised to see a small privet hedge in his front garden begin to vibrate when they called his number. A pair of pants, believed to belong to the man were also found at a nearby bus stop beside a pool of vomit.
