The Ig Nobel Prizes are a parody of the Nobel Prizes and are given each year in early October for ten unusual or trivial achievements in scientific research.

The prizes are presented by genuine Nobel laureates, originally at a ceremony in a lecture hall at MIT but now in Sanders Theater at Harvard University.

These are pretty awesome and some are hilarious. Here a few of my favorites:

Public Health: Jaroslav Flegr, Jan Havlíček, Jitka Hanušova-Lindova, David Hanauer, Naren Ramakrishnan, and Lisa Seyfried, for researching whether owning a cat is mentally hazardous.

Nutrition: Raquel Rubio, Anna Jofré, Belén Martín, Teresa Aymerich, and Margarita Garriga, for their study entitled "Characterization of Lactic Acid Bacteria Isolated from Infant Faeces as Potential Probiotic Starter Cultures for Fermented Sausages."

Archaeology: Brian Crandall and Peter Stahl, for "parboiling a dead shrew, and then swallowing the shrew without chewing, and then carefully examining everything excreted during subsequent days — all so they could see which bones would dissolve inside the human digestive system, and which bones would not."

Probability: Bert Tolkamp, Marie Haskell, Fritha Langford, David Roberts, and Colin Morgan, for discovering that the longer a cow has been lying down, the more likely it will stand up, and that once a cow stands up, you cannot easily predict how soon it will lie down again.

Physics: Alberto Minetti, Yuri Ivanenko, Germana Cappellini, Nadia Dominici, and Francesco Lacquaniti, for concluding that some people could run away a body of water, if both were on the moon.

Here's a full list of Ig Nobel Prize winners.
