Daft Punk's name is a result of someone mocking them!

Daft Punk is one of the most successful French house music acts in the world. It was started by Guy-Manuel de Homem-Christo and Thomas Bangalter. The pair originally formed an indie rock trio called Darlin, when they were still in school.

The duo has admitted that they formed the band because at that point 'everybody wants to be in a band.' Apparently they weren't that great because a negative review of their act said that it was 'a bunch of daft punk.' That struck Bangalter and Homem-Christo so much that they used it as their new name!
