Three missionaries were caught by cannibals and brought before the chief who said that they could go free if they could pass a test or else they would be eaten. The test was for each of them to go into the forrest and get 10 pieces of fruit.

They all go into the forrest escorted by guards and the first missionary comes back with 10 apples and presents them to the chief. The chief then says that for the second part of the test the missionary must shove all of the fruit up his ass without changing his facial expression or he will be killed.

Figuring he has nothing to lose he tries to shove the first apple up his ass and try as he might he grimmaces before the first one gets in and he is killed on the spot.

The second missionary comes back bearring 10 grapes and presents them to the chief where he learns the second part of the test. He figures no problem and slips the first one in, then the second, third and so on until he gets to the ninth one and then he lets out this great big chuckle whereas he is slain on the spot.

The second missionary gets to heaven where he meets the first missionary. The first missionary asks him "what happened, you were doing so good?"

The second missionary replies "I couldn't help myself, I seen the third guy coming back with watermelons!"
