A few highlights from participants in the 2009 Ig Nobel Prize ceremony:
Paul Krugman describes his muffed 24/7 Lecture (and thereby becomes one of the few famous economists who quickly, publicly admits being wrong about something).
2009 Ig Nobel Prize winners Stephan Bolliger (Is it better to be smashed over the head with a full beer bottle or an empty one?) and Peter Rowlinson (Cows who have names give more milk than cows that are nameless) describe their research. (These are interviews, conducted just hours before the ceremony, by Rhitu Chatterjee for the radio program The World. Starts at about the 18-minute mark on this podcast.)
Minordomo Peaco Todd gives an inside look at how the ceremony unfolded.
2009 Ig Nobel Prize winner Dr. Elena Bodnar explains and demonstrates her invention (a brassiere that can be quickly converted into a pair of protective face masks) on the TV program Daily Planet. Starts at about the 6-minute mark).
