So five sailors and a woman were shipwrecked on a deserted island. After a few weeks, they were becoming very horny. So they made a deal: Each sailor would get to have sex with the woman for a week, then the next sailor would get a week, and so on. The sailors got sex every five weeks and the woman got all the sex she wanted, so everyone was happy...
Until the woman died.
The first week was alright.
The second week was a little rough.
The third week was getting pretty bad.
The fourth week was really bad.
The fifth week was terrible.
The sixth week was absolutely unbearable!
...
So they buried her.
