Two men and a woman are stranded on an island

Two men and a woman are stranded on an island after a plane crash. Resourceful, they waste no time, build a house, find food and water, and globally have it good. After one month, the woman goes to the two men and says:

"Okay guys, let's be frank. I have my needs, you have your needs, let's do it. We'll take turns, one day it's you", she says to the first guy, "and the other day it's the other".

And so they have a whale of time taking turns, enjoying their business together for one whole month. However, unfortunately, the woman dies after that month, because of a rotten banana or whatever. The two men mourn the loss of their playmate and partner for the following week. Then, one man goes to the other and says:

"Okay man, let's be frank. I have my needs, you have your needs, let's do it. We'll take turns, one day it's you, and the other day it's me."

And so they have a good time taking turns, enjoying their business together for one whole month. The first man then goes to the other and says:

"Okay man, I need to talk to you.

\- Yeah, me too actually.

\- We had a fun month, but I think we should stop.

\- Yeah, I felt this way too. I feel what we're doing is not natural.

\- That's right. Let's stop."

So they nod their head in common understanding. The second man then says:

"Well then, shall we bury her?"
