A U.S. government agency has earned a literature prize for issuing a report about reports about reports -- and concluding that a new report ought to be prepared to sum it all up.

The government’s General Accountability Office was held generally accountable for the May 10 report at the 2012 Ig Nobel awards, an annual celebration of achievements in the arts and sciences that make people laugh -- and ultimately, hopefully, makes them think as well.

The GAO report, which carried the stultifying title “Actions Needed to Evaluate the Impact of Efforts to Estimate Costs of Reports and Studies," won the Literature Prize in this year’s ceremony, which was held Thursday evening at Harvard University's historic Sanders Theatre.

Master of ceremonies Marc Abrahams, the editor of “the Annals of Improbable Research,” said the 22nd Ig Nobel prizes were filled with hair, coffee, fish, opera singers, and paper airplanes. He was referring to the various awards, of course, which spanned studies into dead fish, why hair turns green and more.

But while humorous, the awards are also serious stuff: Abrahams enlisted five genuine Nobel laureates to hand out the prizes.

On hand for the ceremony were Dudley Herschbach (chemistry, 1986), Rich Roberts (physiology or medicine, 1993), Roy Glauber (physics, 2005), Jack Szostak (physiology or medicine, 2009) and Eric Maskin (economics, 2007).

Abrahams also strives to keep the ceremony entertaining; economics professor Maskin was given away in the Win-a-Date-With-a-Nobel-Laureate Contest. And to keep things moving, the winners -- who often fly in at their own expense from around the globe -- are permitted just 60 seconds to deliver their acceptance speech.

That limit is enforced by “a pair of cute-but-implacable eight-year-old girls.”

NEUROSCIENCE PRIZE
U.S. scientists Craig Bennett, Abigail Baird, Michael Miller, and George Wolford were awarded the Neuroscience award for demonstrating that brain researchers, by using complicated instruments and simple statistics, can see meaningful brain activity anywhere — even in a dead salmon.

CHEMISTRY PRIZE
Johan Pettersson [SWEDEN and RWANDA]. for solving the puzzle of why, in certain houses in the town of Anderslöv, Sweden, people's hair turned green.
