It's the day after Thanksgiving - and that means that it's time for Science Friday's annual broadcast of the Ig Nobel Awards ceremony.
Some awards go to scientists that have deliberately done silly things.
Others go to scientists that have caught the eye of the awards committee unintentionally. This year's awards were presented in October at a star-studded ceremony at Harvard University, and included song, drama, and dance. Richard Roberts, Dudley Herschbach, Robert Wilson, and William Lipscomb deliver their a capella tribute to 99 bottles of beer. They exceeded the time limit of thirty seconds, forcing the referee to whistle them off stage. Master of Ceremonies Marc Abrahams, editor of the Annals of Improbable Research, holds an Ig Nobel Prize.
