“[Researchers] report that some macaques frequently rub or tap stones around their genitals… .
In other words, the monkeys appear to engage in ‘a form of self-directed, tool-assisted masturbation’ …”
—The New York Times

The macaques have been getting their rocks off,
Using tools to help bring their macoques off.
Monkey biology
Thrives on geology.
Rubbing stones on their zones knocks their socks off.
