Footage of a monkey hopping around, yelling and throwing things at a woman wearing a fox hat.
The video, captured on October 22 in a Russian petting zoo, shows the monkey called Focus becoming agitated as he sees the woman's hat.
"Even when she took it off, he still was literally hating her. But then I put it on and I immediately became the subect of his attacks, too," the filmer wrote.
"We even let him touch the hat when the workers let him out of the cage, but he still didn't like the idea."
