The star plays home help Virginia Chance in the comedy, and to promote the upcoming third season, Plimpton has pledged to visit one fan in character - along with her onscreen husband, played by Garret Dillahunt.
She tells Entertainment Weekly, "I think it says a lot about my commitment to promoting the show. People are always trying to come up with creative ways of engaging the viewers. And I thought well, I play a housekeeper on a show, what if I went and cleaned the house of Raising Hope's biggest fan. In my uniform. I am excellent with laundry."
Hopefuls can enter by submitting their best 'Awkward Family Photo' online and series creator Greg Garcia will select the winner from the top 10 finalists. The stars will make their cleaning visit before the end of the year (12).
