Nobel laureates help hand out the awards at the Ig Nobel ceremony, which is a mix of theatrics, music, and comedy.
Among the other 2012 Ig winners were Anita Eerland, Rolf Zwaan, and Tulio Guadalupe for a study entitled "Leaning to the Left Makes the Eiffel Tower Seem Smaller." It took the Psychology Prize.
The Medicine Prize went to Emmanuel Ben-Soussan and Michel Antonietti for "advising doctors who perform colonoscopies how to minimize the chance that their patients will explode."
A paper entitled "Walking With Coffee: Why Does It Spill?" earned the Ig Nobel Fluid Dynamics Prize for Rouslan Krechetnikov and Hans Mayer.
The only winner that did not send a representative to the ceremony was the U.S. Government General Accountability Office. It was honored with the Ig Nobel Literature Prize for issuing "a report about reports about reports that recommends the preparation of a report about the report about reports about reports."
I hope they wrote a report of that somewhere.
