A parody of the Nobel Prizes, the Ig Nobel Prizes are awarded each year in mid-September, around the time the recipients of the genuine Nobel Prizes are announced, for ten achievements that "first make people laugh, and then make them think". Commenting on the 2006 awards, Marc Abrahams, Editor of Annals of Improbable Research and co-sponsor of the awards, said that "[t]he prizes are intended to celebrate the unusual, honor the imaginative, and spur people's interest in science, Medicine, and technology". All prizes are awarded for real achievements, except for three in 1991 and one in 1994, due to an erroneous press release.
