(Long & Dirty) A pilot, co-pilot and a stewardess survive a plane crash

So there is this plane crash above the Atlantic ocean and only the pilot, co-pilot and a stewardess survive. They manage to make it to an island and set up some little camp. After the first week, they realize that surviving is not enough. The pilot asks the stewardess: " Listen, I really need some sexual action, it´s been too long and i´ll go crazy." So the stewardess replies: "if you´re okay with it, and he´s okay with it, we can rotate every day. One day you, one day him." After the co-pilot agrees, the stewardess proceeds to oblige and starts with the pilot. This goes on for a little over a year, until the stewardess sadly catches some unknown jungle disease and dies. The pilot and co-pilot, both heartbroken, look at each other and say:" What should we do now?" The pilot reluctantly says: "I guess there´s no other option: one day you, one day me...." And this goes on for another month. At the end of the month, the co-pilot says:" Listen, I´ve had enough, I can´t go on like this." The pilot agrees and asks what they should do next. The co-pilot tells him: " I think we should burry her now.."
