As of 2001, there are roughly 6 billion people on the planet. Assuming each one takes a dump once a day, there are 6 billion times a day at least that the anus does it's work. Truly this is proof of its thorough design and well crafted construction. Unless of course you don't believe anything designed the anus. Anyways.
Even more common than dump taking is fart?ing, also done through the anus, that most durable and noble of organs.
