They leave in the morning with handcuffs, a dog and a rifle.
Upon arriving to a tree where a gorilla is perched, the hunter tells his friend his technique: “I will go up that tree and shake it so hard the gorilla will fall.
As soon as he hits the ground, the dog will bite him at the balls and while the gorilla will try and get rid of him with both hands that’s when you cuff him and he’ll be captured.”
His friend then asks him:” OK but what’s the rifle for then?” to what the hunter answers:
“If ever, I’m the one to fall, shoot the dog!”
