I'm glad I'm not an astronaut.

This fact is true, because when you're out in space there is no gravity wich you're heart can pull against when its beating. Also the heart is a muscle and every muscles weakens the longer you stay out in space, even if you exercise.

and when such small hearts
how can they be nice to each other?

hmmmm, that's interesting

holy smoke!

How is that possible?

And on christmas day, the astronaut came down to earth and heard all the who-girls and who-boys singing in their who-choir. "How can this be?" Said the Astronaunt, "But, there is no solar energy or 0 gravity. No floating, no freez-dried, no space tube meals." and when The astronaut, heard their happiness, despite the coal plants and nuclear energy that made the Who-lake glow, and covered their cars with soot, and made black snow. The astronaut became overwhelmed and overjoyed, it caused His heart grew 3 times the size. When he came down to sea level there were tears in his eyes, he brought the children unwrapped rocks and substances from space for all the who-race. He did not know, the radiation they brought, but only that concerned with the joy he sought. The astronaut ran down, down to town square, feeling the holiday cheer in the air. "Goodnight, dear greed; and so long to dispair. I am filled with christmas warmth and kindness and Care."

then he turned green and lived in a cave.
