Jafar: WHAT did you say?!
Iago: Evil Viziers are a common stereotype in fiction regarding middle eastern cultures. There's the evil Vizier in the Prince of Persia games, the evil Vizier Abdul Alhazred in King's Quest 6, the evil Vizier Ad Avis in Quest for Glory 2, Iznogoud from Asterix comics, heck, there's even another Vizier named Jaffar in The Thief of Baghdad...
