These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternative Character Interpretation: Is Dilat truly loyal to Iznogoud, or does he serves him and helps him only because he knows his whole situation depends from him? Especially ambiguous in that some of the books contradict each others on that point.
Conversely, it's left ambiguous in later books if Iznogoud does care to some extent about Dilat or just sees him as a pawn. A scene in Who Killed the Caliph especially stands out, as it features Iznogoud being horrified when he realizes Dilat is about to get beheaded and immediatly rushing to save him.
Crosses the Line Twice: Some jokes verge on this. For exemple, in Iznogoud's Childhood, we get a scene of the Caliph interrupting the headman about to cut a fruit thief's right hand. The Caliph forbids it, arguing that he won't be able to atone if he is missing his right hand... and as such orders the headsman to cut his left hand. Then we cut to Iznogoud himself, who explains that part of why he wants to be Caliph is to remove that law about cutting a fruit thief's hand which he finds stupid because he think they should just cut both hands.
Crowning Moment Of Awesome: Iznogoud, of all people, gets one in Iznogoud Finally Caliph, where he is put on trial in what he pretty much knows is going to be a Kangaroo Court, since an entire conspiracy is behind it. He convinces the Caliph to act on his behalf, but the conspiracy has the trial take place right as the Caliph is sleeping, so they can sentence him to death without any interruption. Iznogoud answers by pretending he didn't hear the sentence, until the court is screaming it loud enough to awaken the Caliph. Since awakening the Caliph without a good reason is a major crime, and announcing a sentence isn't a good reason, the court is forced to justify themselves by saying they awakened him so he would help Iznogoud as promised.
Memetic Mutation: Iznogoud's Catch Phrase "I want to be Caliph instead of the Caliph" is often used in European countries when describing a leader's ambitious and unscrupulous underling, or general Klingon Promotion tendencies.
Which in no way prevented photoshops of Sarkozy dressed as Iznogoud from appearing on the Internet shortly after his election, mostly with captions on the subject of "Well, he finally succeeded." There was also a Google bombing mixing Sarkozy and Iznogoud.
