Sounds like a waste of a millstone. Just hack off their arms and legs and push them and their limbs out in shark infested waters. My friend, Richard, says to strip them naked, spray with female gorilla pheromones and throw them in a cage with a teenage male gorilla.

thatll be to much excitement for the gorillas.
graphic warning:

just throw them in with chimpanzees. they are cannibals. they eat there own, alive. they literally rip them apart limb by limb and pluck the eyes out.
