A married couple have been stranded on a deserted island for
many years. One day, another man washes up on shore. He and the
wife become attracted to each other right away, but realize they
must be creative if they are to engage in any hanky-panky. The
husband, however, is very glad to see the second man there: "Now we
will be able to have three people doing eight hour shifts in the
watchtower, rather than two people doing 12-hour shifts."
The newcomer is only too happy to help and in fact volunteers to
do the first shift. He climbs up the tower to stand watch. Soon the
married couple on the ground are placing stones in a circle to make
a fire to cook supper. The second man yells down: "Hey, no
screwing!"
They yell back: "We're not screwing!"
A few minutes later they start to put driftwood into the stone
circle. Again the second man yells down: "Hey, no screwing!"
Again they yell back: "We're not screwing!"
Later they are putting palm leaves on the roof of their shack to
patch leaks. Once again the second man yells down: "Hey, I said no
screwing!"
They yell back: "We're not screwing!"
Eventually the shift is over and the second man climbs down from
the tower to be replaced by the husband. He's not even halfway up
before the wife and her new friend are hard at it. The husband
looks out from the tower and says: "Son of a gun. From up here it
DOES look like they're screwing!"
