Three guys get trapped on an island

Three guys get trapped on an island with cannibals. They get caught and offered a choice, they can either get boiled and eaten, or perform a task and be set free. Of course they all choose to perform a task. So the cannibals send them out into the jungle to pick ten fruits of their choice. They all run off. The first guy returns with 10 bananas. The cannibals tell him that he must now attempt to push them all up his ass without crying. He gets to 4 and breaks down in tears from the pain. The cannibals cook him up and eat him. The second guy returns shortly thereafter with 10 strawberries. The cannibals tell him that he must attempt to push them all up his ass without laughing. Confused but wanting to be set free, he starts. He gets to 9 strawberries but suddenly bursts out laughing. The cannibals cook him up and eat him too. The first two guys are sitting in heaven. Banana guy looks at strawberry guy and says ‘You were so close, why on earth did you start laughing’ Strawberry guy stifles a laugh and says ‘Well, I saw the third guy coming over the hill with 10 pineapples’
