There once was a giant, planet-eating being named Gigantos. Gigantos flew around the cosmos eating planets without a second thought. One day he came upon a planet inhabited by intelligent life. The planet sent its best astronaut, Peter, to stop Gigantos. Peter flew up in his spaceship and tried to plea with Gigantos.
"Please," he begged, "Don't eat us."
Gigantos laughed at him. "You are a puny insignificant life form compared to me. Why should I care about what happens to you?"
Seeing that he would not be able to plea with Gigantos, Peter tried a different approach. "Our planet is small and dirty, wouldn't you much rather eat that big yellow sun over there?"
Gigantos thought about it and decided he might as well eat the sun. After all, he could still come back and eat the planet afterwards. So he put the sun in his mouth and ate it. The sun was hotter than he had thought and it severely burned his mouth. The burns in his mouth were so bad that he wasn't able to eat another planet for over 3000 years, long after Peter's species had become extinct.
The moral of this story is: be content with what you have. Don't try
to eat a sun if you have a perfectly good planet right in front of you.
