Two pilots are flying over a jungle when the plane is shot down.  The two pilots bail out
     before the plane explodes and parachute to safety.  The two men land on the middle of the
 jungle and look around.  All of a sudden they realize that they are surrounded by cannibals.
 
The cannibals take the pilots to their chief.  The chief says, "You gonna be dinner tonight."
 
The pilots got on their knees and begged for mercy.
The chief said, "If you passum bravery test you live.  If you fail, you dinner."
 
The two men agree to the challenge.
The chief said, "You go into jungle and pick 100 piece of fruit and come back.
The two pilots run into the jungle and start picking fruit.
The first pilot returns with 100 grapes.
The chief said, "Now we see if you pass bravery test.  You have to shove all 100 pieces of 
     fruit up ass without laughing. You laugh, you dinner."
 
The pilot drops his pants and proceeds to shove the grapes up his ass.
Before he could get the first grape up his ass he started to bust out laughing.
The chief said, "You laugh, now you die. Why you laugh?"
 
The pilot said, "I can't help it. The other pilot is out there picking pineapples."
