An Englishman, a Frenchman and a Japanese man are stranded on a desert island with little prospect of escape. 'Right,' the Englishman says. 'We need to get organised. The English are obsessed with houses, so I'll build and maintain a shelter, the French are good at cooking, so you,' and he points at the Frenchman, 'can be in charge of the food, and you,' and he points to the Japanese man, 'can be in charge of the supplies.'
They all agree that this is a good arrangement and go off to do their various tasks. The Englishman builds a shelter, the Frenchman starts cooking a meal, and the Japanese man heads off into the interior of the island for the supplies.
The Englishman and the Frenchman never see him again. They try searching for him, but the jungle is very thick and there are wild animals around and it takes their energy away from the business of survival. Twenty years go past....
Finally a boat comes past the desert island, and they're rescued. Hooray! But before they leave, they ask if the crew will help look for the remains of the Japanese man, to see if they can give him a decent burial. So they all head off into the jungle. Carefully they creep along, hacking a path with machetes, going deep into the interior, but there's no sign of the Japanese man. Then there's a rustle - they pause, machetes at the ready in case it's a wild animal - and then - whoosh! out jumps the Japanese man. 'Supplies!' he shouts. 'Supplies!'
Happy April Fool's Day.
