Zhang Bangsheng, a very dedicated Chinese zoo keeper, had to lick a constipated money's bottom for over an hour after the three-month-old Francois Leaf monkey swallowed a peanut whole. The monkey showed signs of stomach problems and was unable to defecate. It was too young to be given laxatives so the only way to encourage it was by licking its behind (Zhang used warm water to clean the area before he began). His efforts were rewarded an hour later when the monkey defecated a single peanut.Picture: Quirky China News / Rex Features
