Cannibals again!

Three friends are trekking through an aboriginal Amazonian jungle when they are captured by cannibals. They are taken to the chief one at a time for their doom. The chief explains how the cannibal society places great value on self control and bravery in the face of pain, and if they can successfully pass a test of bravery they will be allowed to go free. Otherwise they will be eaten. The prisoners are removed to a holding area in a nearby cave and brought out one at a time. Each prisoner, one at a time, is sent into the forest with instructions to return with three fruits. Joe is first, and he returns with three cherries. The chief tells Joe he must now insert the cherries into his rectum, but if he make a sound or so much as a twitch of a facial muscle, he will be killed and eaten at the ceremonial feast. Joe carefully carries out the instructions and is able to complete the task without betraying any of the pain involved. He is taken aside and instructed to remain silent upon fear of death. Next, they bring out Jim who is sent into the jungle for three fruits. Jim returns with three limes, and is given instructions on what he must do to survive. He only just manages to get the limes up his ass without a sound or a facial expression. The last of the campers is then brought out and sent into the forest. Suddenly the other two start laughing. The chief is livid and tells them they have doomed themselves to certain death. Jim says, "Well, I just couldn't help it when I saw Terry come around the corner with those pineapples!"
