3 men are shipwrecked on an island

And start searching the place, but get captured by a cannibal tribe. They are brought to the chieftain, and beg for their lives.

He says, "I will give you a chance to live. Each of you must go out and find 10 of a certain fruit, and then come back. If you do not return, we will hunt you down and kill you."

So they all go out in different directions to look for their fruit. The first guy comes back with 10 apples, and shows them to the chieftain, who then tells him that if he can get all 10 up his butt, they won't eat him. The man worriedly starts putting an apple into his butt, then sliding it as far up as it will go. He gets the first one, then a second, and a third. By the time he starts with the fourth one, it's getting very painful, but he smashes it up there anyway. As he starts inserting the fifth, he decides that he's not going to get to 10, and lets them all fall out. So the cannibals roast him.

The second guy comes back with cherries, and gets the same rule as the first man. He thanks God that he happened to choose cherries, and starts inserting them. He gets the first few in easily, and seems on track to get all 10. However, as he finishes inserting the ninth cherry, he bursts out in uncontrollable laughter and all the cherries fall out. The cannibals roast him as well.

The first man was watching from heaven, and as the second man joins him, the first frantically asks him, "DUDE! You were so close! You totally could have lived! What happened??"

To which the second guy replies, "I saw the last guy coming back with pineapples"
