Holy mackerel! I can write about Tomkat or Brangelina any day, but how often do I get to type the name Lydia Cornell? That's right, Lydia Cornell  and don't you dare ask "Who?" She was the Suzanne Somers of the Ted Knight sitcom Too Close for Comfort in the early '80s. Anyway, she's back  finally!  guesting as "a helpful Victoria's Secret salesgirl" in the Oct. 9 episode of Curb Your Enthusiasm. Sigh. Can WKRP in Cincinnati's Jan Smithers be far behind?
