Karaoke inventor Daisuke Inoue was awarded the humorous Ig Nobel peace prize in a Thursday ceremony at Harvard University for "providing an entirely new way for people to learn to tolerate each other."

Inoue, a 64-year-old Osaka native and one of this year's 10 Ig Nobel Prize winners, was warmly greeted by an audience of 1,200 at Harvard's historic Sanders Theatre near Boston.

Each winner received a handmade Ig Nobel Prize, a medallion made of tinfoil and a certificate from genuine Nobel chemistry laureates William Lipscomb (1976) and Dudley Herschbach (1986), and Richard Roberts (physiology or medicine of 1993).
