The monkeys of Shimla, India, have been known to prowl around in troops looking for tourists to rob or food to steal. Sometimes, they have even been known to bite people.
Indians have a love-hate relationship with the monkeys, who are seen as the incarnation of the Hindu God Hanuman, but also loathed as an urban menace. Their aggressive nature is the main reason why people are warned about getting too close, or showing them disrespect.
As the kid in this video quickly learned, flipping off a monkey in Shimla will guarantee you some instant karma.
