Omar Hassan was, according to the Eleventh Doctor, the best fez maker in Mutter's Spiral. The Eleventh Doctor and Clara visited hid shop in Baghdad in 1930 to replace one of the Doctor's old fezzes. The Doctor stayed and had dinner with him, and he went with the Doctor to help him defeat sand duplicates of Clara and Amy Johnson. He was a skilled backgammon player, beating the Eleventh Doctor multiple times. (COMIC: A Wing and a Prayer)
