Cat conservation law: A cat will always land on it's foots.
1) Take a cat
2) Take a piece of toast (buttered, and slightly brown, almost mulatto)
3) Attatch the bread (butterside up) to the cat's back
4) Drop the cat/toast mixture out of a very high point
Since bread always lands butter side down, and since cats always land on their feet, you get an infinite loop.
