What do we think Jaclyn's famous TV role is?

People seem to notice her obviously from some TV show, but unless I missed something they haven't really said what it is.

I'm guessing her role was on a show centered around a man - a sitcom where she is the pretty wife to a shlubby but well meaning husband. Like an Everybody Loves Raymond or King of Queens type show, a role that's given her a great lifestyle but she secretly resents.
