Ig Nobel Prizes Celebrate Somewhat Suspect Science

The Ig Nobel Prizes honor scientific research that, in the words of Master of Ceremonies Marc Abrahams, "first makes you laugh, and then makes you think." This year's prizes, awarded in late September, include citations for research into mysteriously green hair, potentially explosive colonoscopies, and the creation of equations that model the back-and-forth swing of a ponytail in motion.
