Survivors of a terrible shipwreck

A terrible shipwreck was come.Luckly there has three survivors.Enjoy the follwing joke:

A guy, a pig, and a dog are the survivors of a terrible shipwreck, and they find themselves stranded on a desert island. After being there awhile, they get into a ritual of going to the beach every evening to watch the sun go down. One particular evening the sky was red with beautiful cirrus clouds, the breeze was warm and gentle - a perfect night for romance! Well, soon that pig started looking better and better to the guy, so he leaned toward the pig and put his arm around it. The dog became jealous and growled fiercely at the guy, until he removed his arm from the pig. They continued to enjoy the sunsets together, but no more cuddling. A few weeks passed by, and lo and behold, there was another shipwreck. The only survivor was a beautiful young woman. She was in a pretty bad way when they rescued her and they slowly nursed her back to good health. When she was well enough they introduced her to their evening beach ritual. It was another beautiful evening, red sky, cirrus clouds, a warm gentle breeze; perfect for a night of romance. The guy started getting 'those' ideas again, so he leaned toward the girl and and whispered in her ear, "Would you mind taking the dog for a walk?"
