WASHINGTON — This chimpanzee has disgustingly good aim — unfortunately for one grandmother in Grand Rapids, Michigan, at the John Ball Zoo.

In a viral video shot by former zookeeper Erin Vargo, the agitated ape is seen dancing a little … then defecating.

It then flings the excrement in a high arc as zoo-goers shriek.

The result of the perfect poop shot?

It lands right on an older woman’s nose, much to her shock and chagrin.

“It got grandma,” exclaimed one child.

Yes. Yes, it certainly did.
