Being too big to pass through the monkey's system naturally, the peanut had to be extracted manually. Apparently, that meant licking it out.
Zhang told local reporters the three-month-old lutung was too small for laxatives, so he had no choice but to extract the wayward legume with his lingua. After washing its bottom with warm water (because not doing so would be disgusting), Zhang spent an hour polishing the monkey's pooper before the peanut finally popped out.
