I'd have guessed for sure Cloris Leachman was in her 90s, but that shows what I know. I was mildly surprised by the omission of Mary Tyler Moore, but Wikipedia shows me she's but a spring chicken at 76. Family legend says that my parents only had a boy's name ready for me; when I turned out to be not a boy they had to scramble, and my dad named me for MTM's Laura Petrie character from the Dick Van Dyke Show.
