"Doc" Beardsley : "Sometimes inventing is just about combining the right things. For instance, it's a known fact that cats always land on their feet and never on their backs, right? Right! And it is also a well known fact that when you drop a piece of buttered toast, it always lands butter side down, right? Right! I once super-glued thirty seven pieces of buttered toast to the belly of a cat, with the buttered side facing towards the cat. Whenever you tried to drop this buttered toast cat, it would never hit the ground because the opposing forces canceled each other out. This was basically how I overcame the challenge of levitation."
