Dot Cotton

Dot Cotton was a fictional character who appeared in the British soap opera EastEnders. Clara Oswald described her as a "famous Cockney chimney".

During the Twelfth Doctor's imprisonment in The Prison, Clara took one of Class 2A's art lessons. She asked the students to paint a placard with the phrase 'SAVE THE DOCTOR', but instead they got confused and began to paint 'SAVE DOT COTTON'. (PROSE: The Blood Cell)
