We got to know Alison Arngrim as that bitch Nellie Oleson on Little House on the Prairie. Back then, she taunted Laura Ingalls.
That was then. Now, the actress was seen as the Wicked Witch of the West terrorizing Dorothy at the Wizard of Oz Festival Gingham Gala Riverboat Cruise in Hannibal, MO.
Whether Arngrim is a bitch or a witch, we still get a twitch for her!
