Witchfinder General

From Tardis Wiki, the free Doctor Who reference

The Thirteenth Doctor used psychic paper to pose as the Witchfinder General to Becka Savage. However, James I, who believed that a woman could not be General, interpreted the psychic paper as stating her to be Witchfinder's Assistant and took that Graham O'Brien was Witchfinder General, to which he played along.
