Here's your important life lesson for the day: don't ever be rude to a monkey.

In this video, a young man in India decides to give the finger to a monkey, unaware that the monkey has a bit of a temper. And by "a bit of a temper," we mean the animal immediately lunges at the guy's head and throws him down to the ground like a bunch of rotted bananas.

It's like a WWE fight spontaneously just broke out, egged on by the guy, who, really, got what was coming to him. Let's hope this Dawn of the Planet of the Apes-type revolt doesn't catch on elsewhere in the animal kingdom, though. Cats are already pretty agitated and we don't need them taking out their frustrations in physical form by scratching out our eyes.
