Faust

Faust was a play by Johann Wolfgang von Goethe inspired by an adventure he once had with the Eighth Doctor, in which a Bacchanite bartender tried to use wine at a Viennese tavern to create illusions of personal sorrow to capture his patrons. (PROSE: The Sorrows of Vienna)

Faust was mentioned by the Fourth Doctor when describing the odds of all the animals in the London Zoo trying to escape on the same morning. (PROSE: Stanley)
