I remember Frank Carson telling this joke. fuckin brutal.
A yank, an English fella and a chink crash land a plane on a deserted island.
the yank takes control of the situation and says "OK. We need to get organized here."
they need to sort out the food and water situation and gather some wood for a fire.
He turns to the chink and says "You go and fetch us some supplies in the jungle while we build a fire and try and make contact with any passing ships."
the chink disappears for a week in the jungle and they decide they better go and look for him.
they're creeping through the jungle for a day or two when they suddenly see the bushes rustling and the chink jumps out and says...
SUPPLIES!
