Caliph (The Longest Story in the World)
From Tardis Wiki, the free Doctor Who reference
The Caliph was a man of high royalty who ordered a girl to entertain his court and him with a story. If the girl did not entertain them, she would die. Her life was spared when she told the Caliph a story of an old man and his grand-daughter. (PROSE: The Longest Story in the World)
