Readers of this blog know the risk of doing a good deed for a monkey. There was the Chinese fellow who took the trouble to teach his monkey martial arts, only to have them use their skills to attack him.
And there was the handicapped veteran who forgave his service monkey for an attack that landed him in the hospital - only to be attacked again the next week.
Sadly, another man in China had to learn his lesson the hard way.
A Chinese man who saved a one-armed, one-legged monkey says the primate has paid him back - by killing all of his chickens.
Li Chun, from Menghai village, Yunnan province, says the monkey has become a member of his family since he nursed it back to health.
It has become to devoted to the family and performs many chores around the home - but it also copies everything Li does.
When it saw him crack some eggs to make a meal it went into the hen coop and smashed all of the eggs it could find.
And when Li slaughtered a chicken, the monkey copied him and has since killed about 80 chickens, reports the Chuncheng Evening Post.
"From then on, whenever it's not occupied, it jumps into the chicken pen, and kills the chickens, no matter how big or small, and tries to pluck them," said Li.
"His record is nine chickens in one day. The lesson I have learned is to never slaughter a chicken in front of a monkey."
