A man invites a friend to a hunting party

A man invites a friend to a hunting party in Africa, We’re going to hunt gorillas.

I’ve never done such a thing, how do you even hunt gorillas ?

Well it’s quite easy, all you need is a dog, a big bag, and a rifle.

OK… And how do you use them?

Simple as that : I climb the tree, then I scare the gorilla to make it fall on the ground.

When the gorilla falls, the dog is trained, and will bite the gorilla’s balls,

and when it faints due to the pain, we put it in the bag. Easy.

Then why the rifle?

If I fall first, you shoot the dog.
