Daisuke Inoue tells all over at The Appendix:

Last year I received a fax from Harvard University. I don't really speak English, but lucky for me, my wife does. She figured out the letter was about the Ig Nobel Prizes, awards that Harvard presents for inventions that make people laugh—and then make them think. I was nominated for an Ig Nobel Peace Prize as the inventor of karaoke, which teaches people to bear the awful singing of ordinary citizens, and enjoy it anyway. That is "genuine peace," they told me.
