Where else but on Japanese television would one find something called Human Trebuchet; in which a person is flung by a large, wooden contraption into a distant net? And it looks pretty easy to build ... and suddenly, you are never late for an appointment again.
First employed by the Romans for use in siege warfare, and later by King Arthur to fling cows in Monty Python and the Holy Grail, the trebuchet was a forgotten weapon until recently. I know that if I had one I'd charge the neighborhood kids $5 per ride and get rich quickly. "Well Brandon, I hear your mom calling you for dinner, so it's time for you to go. Let's see, that's Oak Street, right?" KA-CHUNK!
