There is ship wreck at sea and only 1 woman and 5 men survive.
They cling to a life raft and float to a deserted island.
After spending several weeks on the island,
they all begin to get very lonely and sexually deprived.
So they come to the following agreement:

Each man will marry the woman for a week.
So the first man has her for one week,
then the second man has her for the second week, and so on.
Everyone will now be getting sex and they all agree to it.

This goes on for five years and everyone is happy.
Each man gets sex every fifth week and the woman gets to have sex
whenever she wants and with a different man every week.

A few weeks into the fifth year, tragedy strikes and the woman dies!!!

The first week isn't too bad,
the second week starts to get bad,
the third week is getting worse,
the fourth week things are just awful
and by the fifth week

the men can't stand it any longer and they bury the woman.
