Iznogoud 4 - Iznogoud and the Magic Computer - René Goscinny

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.
