Actor Tim Conway, who voiced the character Barnacle Boy on "SpongeBob SquarePants," has died. "SpongeBob" showrunner Vincent Waller announced in September that Conway wouldn't be returning to the cast because of health issues. Conway was known to an earlier generation who watched him on "The Carol Burnett Show" in the 1970s. He also starred in the 1960s sitcom "McHale's Navy." The six-time Emmy winner was 85 years old.
