Comedian George Carlin, a provocative hero famed for his routines about drugs and dirty words, died of heart failure at a Los Angeles area hospital on Sunday, a spokesman said. He was 71. George Carlin was an icon on my days as a youth. He pushed the envelope in a day when no one else would. He was reverent, sometimes vulgar but always entertaining, even in his later years.
