John, Bob and Mike are on a boat far out at sea when it is sunken by a violent storm...

Early the next morning they wash up on an island. As soon as they pick themselves up they are immediately surrounded and held at spear-point by the island's natives.

The leader of the natives approaches the three and says "If you can complete one task for us we will let you in leave in harmony with us for the rest of your lives."

The three agree and ask what is required of them. The leader says "Go into the forest and each of you find as many of one fruit as you can and return for further instruction."

So they head out into the forest to search for fruit. John is the first to return. He comes back with both arms full of apples.

The leader says to John "if you can shove every one of those apples up your ass without making any kind of noise or facial expression we will let you live."

John reluctantly agrees. He starts to stick the first apple up his ass and he screams in pain, so the natives kill him.

A few minutes later, Bob returns with a whole bunch of cherries. The leader tells him the same thing. Bob starts sticking cherry after cherry up his ass flawlessly. When he gets to the very last one he starts laughing hysterically. The leader and the natives can't believe he failed at the last cherry, but nonetheless they kill him.

John and Bob are up in heaven telling each other what happened. Bob tells John about how he got to the very last cherry and then just laughed which resulted in his death. John asks "Why the hell did you laugh? You had it in the bag!" Bob says "I saw Mike coming back with watermelons."
