SING a DUET at karaoke

Most people credit the invention of karaoke to Japanese businessman Daisuke Inoue in 1971. Awarded the Ig Nobel Prize at Harvard in 2004 for ‘providing an entirely new way for people to learn to tolerate each other’, his acceptance speech included a karaoke rendition of ‘I’d Like To Teach The World To Sing’ which won the longest standing ovation in the history of the awards. Inoue doesn’t own a patent on karaoke, so he’s never made any money from it. However, he has patented a cockroach powder that specifically targets infestations in karaoke machines.
