A guy, a pig, and a dog are the only survivors of a terrible shipwreck, and they find themselves stranded on a desert island.

After being there for awhile, they get into a ritual of going to the beach every night to watch the sun go down.

One particular evening, the sky was red with beautiful cirrus clouds, the breeze was warm and gentle — in short, a perfect night for romance!

Well, that pig started looking better and better, and pretty soon the guy rolled towards the pig and put his arm around it.

The dog was not very happy with this, and growled fiercely at the guy until he moved his arm away.

The three of them continued to enjoy the sunsets together, but there were no more efforts at 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 completely well, they introduced her to their nightly beach ritual.

Then came another gloriously beautiful evening — red sunset; delicate cirrus clouds; gentle, warm breeze — again, perfect for romance.

The guy started getting “those ideas” again, so he leaned over to the girl, and said,

“Um… would you mind taking the dog for a walk?”
