In a scene reminiscent of two drunk blokes duking it out in your local on a Saturday night, crazy footage of two male gorillas at an American zoo has gone viral after the pair exchanged blows in a brutal fight.
The clip was caught on camera by Shannon W. Olsen at Henry Doorly Zoo in Omaha, Nebraska.
The fight starts as one of the primates stalks his opponent down a hill, before then launching into him.
Then all hell breaks loose…
And, yes, it is the same zoo where a gorilla smashed the viewing window to its enclosure last year.
These guys clearly have some pent up aggression from their time in captivity.
