- Adaptation Displacement: The few American, English or Latin American people who have heard of this are either thinking of the infamous PC game, or the pretty decent Animated Adaptation.
- Alternative Character Interpretation:
- Is Wa'at Alaaf truly loyal to Iznogoud, or does he serve him and help him only because he knows his whole situation depends on him? Especially ambiguous in that some of the books contradict each other on that point.
- Conversely, it's left ambiguous in later books if Iznogoud does care to some extent about Wa'at 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 Wa'at 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 off 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 off 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 off a fruit thief's hand which he finds stupid because he think they should just cut off both hands.
- "Funny Aneurysm" Moment: Seeing the Caliph being convinced Iznogoud is a nice, well-meaning and caring friend despite every evidence of the contrary suddenly becomes tragic after Iznogoud's Childhood, where it's revealed Iznogoud really was that nice and caring friend to him as a child before being turned into his present-day Jerkass by a potion, and this once genuine friendship very likely is why the Caliph cannot accept the idea of his once best friend being evil.
- Memetic Mutation: Iznogoud's Catchphrase "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, or to describe someone whose ambitions far exceed their abilities.
- 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.
- What Do You Mean, It's Not Political?: Despite physical and psychological similarities, Iznogoud was not inspired by French president Nicolas Sarkozy.note (He did, however, meet Jacques Chirac at one point.) 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. Moreover, an Iznogoud book written after Tabary's death in 2011 made extensive use of the similarity, and Sarkozy also won the 1999 Iznogoud Award, which is presented to the person who made the year's most high-profile failure.
- The Woobie: Wa'at Alaaf, for being Iznogoud's personnal Chew Toy.
YMMV / Iznogoud
