Shipwrecked on an island with canibals

An American, an Englishman and a Canadian are sailing with a boat on the ocean when a storm breaks out and they shipwreck on an island. Soon they are met by a tribe of Canibals that inhabit this island. "We will eat all of you" their chieftain says "unless you can complete our quest!"

"what is that task?" the shipwrecked ask. "You have to go into the jungle and bring back two different fruits." the chieftain explains.

So the three men hurry into the jungle and after a while the Englishman comes out holding an apple in one hand and a pear in the other. The chieftain looks at him and says: "Now you have to put both those fruit in your butt without laughing! If you can't, we kill you!"

The Englishman agrees with the task, since he can't argue with a whole tribe of armed canibals. So he starts with the apple, but not even halfway through he chuckles and is immedeatly killed with a spear.

After a few minutes the Canadian comes out with a strawberry and a grape. The chieftain looks at him and also tells him the same: "You have to put both of those fruits into your butt without laughing! If you can't, we kill you!"

The Canadian also complies and starts. He gets the strawberry in with no problems but after shoving in the grape he suddenly breaks out into histerical laughter and is killed shortly afterwards.

Later, in heaven the Englishman meets the Canadian. "I couldn't do it without laughing" he said "I guess you had the same problem." "Acctually no -" the Canadian answers. "I almost put both the fruit up my butt without laughing, but before i finished i saw the American come out the jungle with a pineapple and a melon."
