Dumb Muscle: Asher has the body of a gorilla and just one brain cell.
Early Installment Weirdness: The ultra-rare "numberless" Zbeng is very odd to those who are familiar with the later books. For once, it's not just "Zbeng", but a collection of different comics Uri Fink was making at the time.
Man Child: The school's Principal is much more interested in cartoons and toys then teaching.
A Man Is Not a Virgin: Subverted in an early comic. Shortly after (virgin) Gal and Sigal (temporarily) broke up, Jinji invites Gal over to have sex with a Scandinavian tourist, along with another tourist. After briefly debating the dilemma, complete with a Good Angel, Bad Angel scene, the story cuts to Jinji calling Gal a coward, only to reveal that Gal is happy he didn’t do it, as the tourist gave Jinji and his other friend an STD.
Mood Whiplash: One story from the early 2000's involved the cartoonist trying to shoehorn himself into the cast. First as "one of the guys" (much to the dismay of the teenage protagonists), then as one of the characters' uncle (with even less success), and finally as a teacher at their school, before the characters finally intimidated him away. Gal then ponders what made him want so much to live in their fictional world. We then cut to Ouri Fink's office, where he stares, eyes full of dread, at a live-TV image of the burning World Trade Center.
Raging Stiffie: Jinji sits behind a very attractive female classmate at the beginning of the new school year, when a new regulation came into effect saying students have to stand up when the teacher comes in.note That didn’t happen in Real Life, although it was suggested at a time when students’ respect for teachers in Israel was at a grave low point. Jinji stares at the girl’s rump for a long while before noticing he has to get up too, at a rather compromising position. Fortunately, he notices the token gay classmate sitting behind him and his stiffie is scared away.
Running Gag: In early stories, characters running away to join a Trappist Monastery.
Sadist Teacher: Mrs Zaafani. By her own admission, her only joy in life is screaming at people. This was emphasised in the short-lived live-action adaptation, in which she turned from being just very impatient with her students to overtly relishing in tormenting them, as seen in the pilot:
Zaafani: You will call me ‘Mrs. Zaafani’... and I will tearnote Homophone of ‘call’ in Hebrew you to shreds. (Evil Laugh)
She Cleans Up Nicely: One story had Jinji discovering, to his horror, that girls fart and burp too, but it turns out Zaafani has never farted or burped in her life, which explains why she’s so mean. When she’s encouraged to finally let it all go, she turns out to be quite beautiful and turns much nicer, but it turns out it was All Just a Dream.
Soap Box Sadie: Sigal is more than a little devoted to her political ideals.
Speaking Like Totally Teen: In one story, the adults started talking to the teenagers with then-current slang, to communicate with them better. The teens got sick of it and reacted by speaking in Antiquated Linguistics, making their parents mad at their ‘ungratefulness’ at their efforts to relate to them.
Status Quo Is God: To the point where changes to a character's haircut are treated like a big deal.
Sweet Polly Oliver: Osnat dressed up as a solider to visit her boyfriend at the base he serves at.
Teen Genius: Yaron can make teleporters, potions and robots and he's only 16!
Terrible Interviewees Montage: Zbeng! 1 starts with all the characters getting interviewed by Uri Fink to be the main character in his new comic and getting rejected. In the end Uri realized that comic should be about ALL of them.
The Pollyanna: Despite living in a cardboard box, Asaf is easily the happiest member of the cast.
Twin Switch: Gal makes Yaron pull it off from time to time, it never works.
The Vamp: Maya's entire character is based on her ability to wrap the boys around her finger.
Two Decades Behind: A reader once commented on the clothing the teens wear being somewhat outdated. Fink explained that it’s somewhat inevitable, saying that if he tried to go to schools and draw the students’ clothes and take notes he’d ‘spend the night in Abu Kabir◊’.
The Unsmile: A short story had Maya and Stav both wear a device that forced their lips into a smile. While no-one even noticed Maya was wearing it, when people saw Stav that way they ran away screaming in terror.
Unusually Uninteresting Sight: Even without counting numerous instances of All Just a Dream, the cast has encountered aliens, demons, angels, outright miracles from God, time travelers, and more. This doesn't really seem to shock them.
