Jouni Kalervo Hynynen (born February 15, 1970, in Joutseno, Finland) is the guitarist/vocalist in Kotiteollisuus, a Finnish heavy metal band. He also writes the band's music along with his bandmates, and contributes majority of the lyrics. He has also written a book, hosted a reality TV show called "Äijät" ('Gaffers') with Jone Nikula and been a columnist for newspapers. He is known not only for his desperate and dark lyrics and his extraordinary looks and attitude, but also his sense of humour, which can be seen, for example, in NO SORI!, where Hynynen is the "special editor-in-chief".
