When a cat is dropped, it always lands on its feet, and when toast is
dropped, it always lands with the buttered side facing down. I propose to
strap buttered toast to the back of a cat; the two will hover, spinning
inches above the ground. With a giant buttered cat array, a high-speed
monorail could easily link New York with Chicago.
Honorable Mention:
The reason hot-rod owners raise the backs of their cars is that it's
easier to go faster when you're always going downhill. Besides, they get
better gas mileage that way.
