A family visiting the Henry Doorly Zoo & Aquarium in Omaha decided to check out the gorilla exhibit but it ended abruptly when a massive Silverback gorilla tried to break the glass partition with its fists.

In the video, you see two small children banging on their chests and mocking the gorilla that's behind the wall. When the massive mammal spots the teasing kids, it rushes the glass wall and puts several cracks in it.

The video was uploaded by YouTube user BULL DOG on Thursday and has over 2 million views. 

The gorilla clearly wasn't in the mood for any visitors that day.
