A Francois' Leaf Monkey is one of the smallest monkeys in the world. They also happen to be one of the more rare species of the animal.

A caretaker in the zoo where a 3 month hold Francois' Leaf monkey was kept found out that it had swallowed a peanut.

Due to its small size it could not effectively pass the peanut. And since it was so young they couldn't use medication on it yet. So it was going to need help.

Zhang Bangsheng, the caretaker in question, decided to do the only thing possible to save the monkey's life: lick the monkey's butt to spur it to defecate.

You think that's the bad part?

Nope. He had to do it for AN HOUR.
