Susan B. Anthony is featured in a deleted scene[1] from the episode "Mark Loves Dick".

Susan B. Anthony is able to change America, even after her death. Women zombies have come a long way. At one point, the undead heavily discriminated against reanimated female corpses. Lady zombies (or "lombies," as they don't like to be called) were paid lower wages for the same duties as male zombies, often receiving a cerebellum where a male would receive a frontal cortex. But zombie Susan B. Anthony changed all that.
