WASHINGTON — A family visiting the silverback gorilla display at a zoo got quite a scare this week when one of the animals suddenly got a burst of anger and flung himself at the family on the other side of the glass.

The glass cracked, but did not shatter, but sent the family, particularly the small children who moments before were “aping” the animal in typical glee, screaming and fleeing. A family member filmed the whole thing.

According to this account at WABC-TV in New York, the incident happened at Omaha’s Henry Doorly Zoo & Aquarium. The family is unidentified, but the video has, not surprisingly, gone viral.
