The annual IgNobel Prize awards honor people whose achievements "cannot or should not be reproduced." Ten prizes are given to people who have done remarkably goofy things -- some of them admirable, some perhaps otherwise. The prizes are presented at Harvard University, and are sponsored by the scientific humour journal Annals of Improbable Research. The first IgNobels were awarded in 1991. They are a parody of the Nobel Prizes.
