Winners were announced last weekend.  Some of my favorites:

FOR PHYSICS:

John Mainstone and the late Thomas Parnell of the University of Queensland, Australia, for patiently conducting an experiment that began in the year 1927 — in which a glob of congealed black tar has been slowly, slowly dripping through a funnel, at a rate of approximately one drop every nine years.

REFERENCE: "The Pitch Drop Experiment," R. Edgeworth, B.J. Dalton and T. Parnell, European Journal of Physics, 1984, pp. 198-200.

WHO ATTENDED THE IG NOBEL CEREMONY: John Mainstone

FOR ECONOMICS:

Gauri Nanda of the Massachusetts Institute of Technology, for inventing an alarm clock that runs away and hides, repeatedly, thus ensuring that people DO get out of bed, and thus theoretically adding many productive hours to the workday.

WHO ATTENDED THE IG NOBEL CEREMONY: Gauri Nanda

FOR BIOLOGY:

Benjamin Smith of the University of Adelaide, Australia and the University of Toronto, Canada and the Firmenich perfume company, Geneva, Switzerland, and ChemComm Enterprises, Archamps, France; Craig Williams of James Cook University and the University of South Australia; Michael Tyler of the University of Adelaide; Brian Williams of the University of Adelaide; and Yoji Hayasaka of the Australian Wine Research Institute; for painstakingly smelling and cataloging the peculiar odors produced by 131 different species of frogs when the frogs were feeling stressed.

REFERENCE: "A Survey of Frog Odorous Secretions, Their Possible Functions and Phylogenetic Significance," Benjamin P.C. Smith, Craig R. Williams, Michael J. Tyler, and Brian D. Williams, Applied Herpetology, vol. 2, no. 1-2, February 1, 2004, pp. 47-82.

WHO ATTENDED THE IG NOBEL CEREMONY: Ben Smith and Craig Williams

FOR CHEMISTRY:

Edward Cussler of the University of Minnesota and Brian Gettelfinger of the University of Minnesota and the University of Wisconsin, for conducting a careful experiment to settle the longstanding scientific question: can people swim faster in syrup or in water?

REFERENCE: "Will Humans Swim Faster or Slower in Syrup?" American Institute of Chemical Engineers Journal, Brian Gettelfinger and E. L. Cussler, vol. 50, no. 11, October 2004, pp. 2646-7.
