Harvey Fierstein

Harvey Forbes Fierstein (born June 6, 1952) is an American actor and playwright, best known for his very gravelly, deep-pitched voice. He voiced Karl in the season 2 episode "Simpson and Delilah". He was asked to return as Karl in the season 14 episode "Three Gays of the Condo", but declined because the script didn't have "that Simpsons twist".
