The poacher agrees but says that his assistant is ill and will need the man to come with him in his assistant's place. The man agrees and so the poacher goes out to the jungle with the man.
The poacher brings a pair of handcuffs, a long stick, a shotgun and a dog. They search through the jungle for about an hour and then spot a male gorilla above in the treetops.
The man asks the poacher what the plan is. The poacher replies "I'm going to climb the tree and, when I get close enough, I'm going to start poking the gorilla with the stick until it falls out of the tree.
The dog is a specially trained dog. When the gorilla falls out of the tree, the dog will try to bite off the gorilla's balls. When the gorilla moves its hands to protect it's balls, you put the handcuffs on it."
This all seems to make sense to the man but he has one question. "What is the shotgun for?" he asks the poacher. The poacher responds: "If I fall out of the tree before the gorilla, shoot the dog."
