The whole idea is that it’s 100 people barehanded vs a gorilla.
Even then, humans low diff with relatively little coordination.
Literally just get two people to strangle the gorilla and another two to distract said gorilla, before having everyone else beat the shit out of it. You can do it with 10 people even.
Hell, if that’s too much, just trick the gorilla into falling off a cliff. We’ve done it before, it’s called a buffalo jump.
Next time, people should ask something like whether we’d win against a hippo. That’s a little less obvious.
