This clip is absolutely terrifying. Course, what in this world could be scarier than two bald, ripped chimps fighting dozens of others in an enclosed space.
This is the moment that two chimps, believed to be father and son, caused a fight to erupt between apes in a zoo in England.
The footage was filmed at Twycross Zoo, in Atherstone, and shows the chimps, both suffering from alopecia, chasing and hitting one another while screeching and grinding their teeth, just before the mass brawl erupts.
The chimps in the video are almost walking proof for evolution – and that is simply what makes them so scary.
