From a Parent's Guide Book:

=========================
You have clearly and calmly asked your kids to pick up their toys and to get ready for bed. It's obvious that they heard you, but they continue to play. Again, with more force and anger in your voice, you state what it is you expect. Once again, no response.
Finally, red faced (trotting in their direction looking something like Edith Bunker) and at the top of your lungs, you repeat your demand that they clean up and get ready for bed. Low and behold, this time they obey. Once again, you are left feeling angry frustrated, and absolutely convinced that it was your anger and frustration that finally motivated them to do what you wanted.
============================

I found that Edith Bunker is a friendly character in a TV show. But what the point to mention in this article? What kind of pose or attitude of Edith Bunker referred to?
