It will probably be easy to say "this whole series", but that is not how TV Tropes work. So, without further ado, here are some examples.
- Pretty much Azusa's every single Tsundere moment in the Live Action series.
- Anytime Onizuka makes a funny face.
- "GTO - The Legend Begins": Onizuka's Slow "NO!" as a dish of freshly made sushi he wants to eat is thrown away.
- "Enter Uchiyamada!": This exchange:Uchiyamada: What are you doing?Onizuka: Nothing, just wetting myself.Uchiyamada: Very interesting.
- When Azusa invites him to stay over at her apartment to study for the exam, he meets her at the school gate with a bulging cloth wrapped around his stuff, including condoms, cologne, his Porn Stash, and a few Noodle Implements like a soft-shell turtle.note
- When the kids force Onizuka to buy them expensive sushi and he weeps for all the wallet pains. Then he seems to drop the worries and starts ordering insanely expensive sushi by the truckload. And when he's eaten half a whale... he up and runs for it, leaving the kids to either pay the bill or escape on their own.
- And THEN he runs into traffic and gets hit by a car, possibly deliberately, and then demands the driver (who happens to be Tomoko's manager) pay his medical bills...AND the sushi bill. And to give Onizuka his clothes.
- Urumi's early day in class. She makes a remark about "Oh cute. A King Cobra." with Onizuka casually thinking 'Hah, no way there's a King Cobra here in Japan.'... cue an actual King Cobra biting him on the crotch. Hilarity Ensues when Onizuka attempts to get the teachers remove the cobra from his crotch. So how did he not die due to venom? Thankfully, it's just a make up made by Urumi done to a harmless, non-venomous snake to make it look like an actual King Cobra.
- After all of Onizuka's schemes to get the whole school to Okinawa fails he decides to go to Ryuji for help, confident that, as Bash Brothers who've had each others backs through thick and thin, he'd give him the 8 million yen even if he has to chop off a finger for it. One Ironic Echo Cut later...Ryuji [nonchalantly picking his nose]: And where would I get ¥8 million? Chop off a finger? Dude! What are you high or something?Onizuka [wearing the mother of all Oh, Crap! expressions]: I may wind up on a tuna boat if you don't help! Out on the Indian ocean!Ryuji [completely uncaring]: Sounds like an ok gig. Maybe then you can pay me back the ¥870,000 you already owe me. I say take it.Noboru: It's true what they say.Anko: Low on money, low on friends.
- When he seems like he won't be be able to get the money he needs, Onizuka bites the bullet gives a big speech about taking responsibility for one's actions, resigns and leaves to work on a Tuna Boat and when he leaves, everyone is in tears...only he got his Benz back from the teacher everyone thought conned him and he got on the ferry to Okinawa.
- Onizuka wants to make the Okinawa field trip to be unforgettable for his students, what's the first thing he's do to achieve it? Places them up in a gender mixed hotel room assignments, of course.Uchiyamada: Are you trying to encourage inappropriate behavior!?
- His response to the protesting Anko?Onizuka: What's the big deal? You're all the same species.
- The Gundam Trio, that's all. Poor Urumi.Urumi: [In tears] I'm rooming with a bunch of alien, sci-fi nuts!
- Even better, it's very likely that Onizuka deliberately arrange Urumi's room assignment as such to punish her for trying to get Miyabi and her posse raped by a group of rich perverts. She gets him back for it, by putting an eel into his shorts. Two guesses on what that eel did.
- The exchanges between students in the ensuing pandemonium are all sorts of hilarious as well.Urumi: Move your greasy Gundam asses to the other side of the room!Female Student: That's it! I'm yelling rape. Rape, rape!!Male Student: Rape?! What are you talking about!? Who'd rape you!?Female Student: And if you want to take a dump, go to the lobby! That's the last thing I want to smell!Male Student: Hey, put that bag down! That's mine!
- His response to the protesting Anko?
