UPDATE April 4, 5:41 a.m. EST:
John Ball Zoo responded to its newfound fame in a Facebook post Monday, clarifying that the woman recording the video was not a zoo employee but a guest.
The zoo said the chimpanzee likes to interact with people. When people laugh or yell in response to its behavior, that encourages it further, which led to Sunday's poop-throwing incident.
The zoo also said it would install new barriers to protect guests from airborne feces and "similar situation[s]."
