A family at Omaha’s Henry Doorly Zoo & Aquarium cut their visit to the gorilla exhibition short after one silverback, evidently in no mood for guests, charged the glass partition, putting several cracks in the pane.

The footage of the close encounter has racked up almost 1.7 million views since it was uploaded to YouTube on Thursday.
