Chimpanzees are running around with grass in their ears and butts at the Chimfunshi Wildlife Orphanage in Zambia. This is the second time a bizarre fad-like behavior has gripped the sanctuary's chimps, but wearing the grass accessories in their butts is a new twist.
“Meanwhile, in the other group, a male named Juma was identified as the possible innovator of the daring new grass-in-butt variation, which spread to most of his group mates within a week, according to the study.”
So apparently it wasn’t just his kink. Most of them had a twig up their ass, lol
