Visitors to Texas’ Houston Zoo recently got an unexpected bonus with the roughly $30 cost of their admission tickets — landing front-row seats to a pay-per-view-level beatdown between a group of angry Gorillas.

Earlier this summer, four angry male Western Lowland Gorillas simply couldn’t wait until closing time to settle their likely banana-related beef, punching, tackling, and kicking each other inches away from the glass barrier of their enclosure as a crowd of horrified patrons looked on.

Though this is far from the first time the animals have gone at it, according to local news outlet KHOU,  one thing is certain — it’s only a matter of time before these brawling creatures land in a cage match with the Paul brothers.
