A Joke about Cannibalism

Three men are stranded in the jungle: a French man, A Japanese man, and an American.
In the jungle, they are found and captured by a tribe of Cannibals.
They are taken to a tent in the village and left for many day, until they are skinny and weak. Finally, the chief of the cannibals comes to pat them a visit.
He tells them "We are cannibals, so we must kill you, but I want you to know not a single part of you will go to waste. We will use your bones for tools. We will feast on you meat. We will use your flesh for canoes. Your sacrifice will allow our civilization to live."
Then, the chief brings out three knifes, and tells the hostages that he will allow them to kill themselves with honor.
The French man take the knife, yells "Viva La France!" slits his neck,and dies.
The Japanese man takes the knife and yells "For Japan!" slits his neck, and dies.
The American takes the knife, and out of nowhere starts stabbing himself. Up and down his arms, in his side, across his legs, just making a mess.
Finally, in his final moments as the chief watches in horror, he yells "Here's your fucking canoes!"
