Comedian George Carlin, whose "Seven Words You Can Never Say on TV" routine lifted him to what he himself described as "a footnote in American legal history" that he was "perversely kind of proud of," died Sunday of heart failure at age 71. Jack Burns, who teamed with Carlin as a disc-jockey duo and later as a nightclub act in the early '60s, told the Associated Press, "He was a genius and I will miss him dearly." Only last week, it was announced that Carlin had been awarded the 11th annual Mark Twain Prize for American Humor, which was to have been presented to him in Washington on Nov. 10.
