This reminds me of a topic that turns up in New Scientist every now and
again. The theory goes something like this: A cat always lands on it's feet,
and a dropped slice of toast always lands butter side down. Therefore, if
you secure a piece of toast (butter side up) to the back of a cat, and then
drop the cat, it will spin indefinitely and create a perpetual motion
engine.
