Chimpanzee flings poop at unsuspecting Grandma.

A grandma left a Michigan zoo with an unexpected (and unpleasant) souvenir after being struck in the face by a ball of poop.

Video shared to YouTube by Jacob Mitchell shows a chimpanzee at John Ball Zoological Garden in Grand Rapids swaying back and forth in its enclosure before hurling the ball of feces up toward the crowd above.

"It got grandma," one onlooker said.

The viral video received more than 1 million views and Jacob encouraged viewers to donate in support of John Ball Zoo and its conservation efforts.

"The sharing of this video aims to shed light on the importance of not taunting/teasing animals residing in zoo habitats," he wrote. "Zoo staff would like to keep animals as calm and comfortable in their habitats as possible. It is critical to not tap on glass, shout at the animals, or attempt to feed them."
