The Japanese are no strangers to the Ig Nobel Prize. Dr. NakaMats, our favorite inventor, won it in 2005 for documenting 35 years worth of meals, and 10 others have also won the silly science award, which is handed out by categories every year by the Harvard-based Annals of Improbable Research.
What an exciting week for Japan! Not only did we land a probe on the moon, but we figured out how to make poo taste good! Very, very important stuff.
