After an airplane crash the pilot, co-pilot and one CA lend on a small island.
The island have fresh water and plenty of fruits so they live there for few months.
One night the pilot says:
"Life is good here but we need to do something about sex!"
They all agree and the CA said:
"OK, I can do it one day with the pilot and the next with the co-pilot"
Life goes on and they have sex with CA however after a year the CA gets sick and die.
After a week with just the two men on the island the captain says:
"What should we do about our sex arrangement?"
co-pilot : " I really miss sex so why don't we just do one day me and the next you?"
Pilot : "I am not really into this but we don't have much choice, let's try"
So during the next two weeks they do it, one day the pilot, the next the co-pilot .
One nigh the pilot says: " I am sorry but I cannot do it anymore, we need to find another solution"
Co-pilot: "me too actually i don't want to do. What should we do?
Pilot :" Maybe we should bury her"
