The Duke of Cheapside was the father of Sally Cheapside. He kept trying to keep her from growing up. However, Sally ended up pregnant, addicted to opium and in love with poet Percy Shelley. The Duke was also in denial about the fact that Sally had killed his wife. After they had been mugged by Mr. Blackadder, Sally insisted that her father did nothing to defend her honour. The Duke responded by yelling "Oh shut your face, you pregnant junky fag-hag!"
