Perusing the day's celebrity birthdays, as I am wont to do in moments of boredom, I discovered that Katherine Helmond (Mona on "Who's the Boss?") turned 79 years young today. I distinctly remember thinking she wasn't a day under 79, when I first starting watching that show. Should that line of thinking be attributed to the untrained eye of a 7 year old or did dear Ms. Helmond not age particularly well?
