Three Explorers Arrive On An Island Inhabited By A Tribe Of Cannibals...

The chief of the tribe captures them and after a long time of hearing the explorers beg for their lives, the chief gives them a challenge. "Okay, you can live, but each of you must bring me ten peices of the same type of fruit." So on their way they go.

The first explorer returns with ten apples. The chief then tells him "now you must put all ten up your butt." After 5 apples, he is going through so much pain that he begs them to kill him, which they do and he goes to heaven.

The second explorer returns with ten blueberries and the chief once again tells the explorer he must insert the fruit up his butt. He is nearly done with nine already inside, when he begins to laugh uncontrollably, to which the chief responds by having him killed. The second explorer then goes to heaven.

When he arrives in heaven, the first explorer asks him "why did you start laughing, you were almost done." The second explorer responds " I saw the third explorer and he was carrying watermelons."
