Dickie was a serious teacher driven to despair and anger by having to teach Beavis and Butt-head. In "Scientific Stuff", she forced them to do another science project, this time partnered with Daria Morgendorffer (ignoring Daria's protests).
In the 2011 revival, she's in the background of Copy Machine but replaced as a speaking character by an unnamed, easily-irritated brunette teacher voiced by Laraine Newman. In an interview with Rolling Stone on the revival, Mike Judge remarked, "We have one new teacher that's in a couple of episodes, a female teacher. I never felt like we had a good female teacher character."
