Iznogoud and the Magic Computer: Iznogoud Volume, 4

In Baghdad, the Caliph's Grand Vizier Iznogoud has one aim in life: to become Caliph instead of the Caliph. The benign ruler, Haroun al Plassid, is blind to his vizier's scheming to get rid of him and generally would rather take a nap. Iznogoud is faithfully seconded by Wa'at Alahf in trying to put his fiendish designs into action.
