- Pretty much every time Araragi runs into Mayoi, he ends up groping her, fighting with her, or both.
- The Insane Troll Logic he uses to explain it is utterly hilarious.
- And the fact that the first time he doesn't do this she gets angry with him.
- In Episode 14 Kanbaru answered her phone introducing herself as Araragi's love slave. She said this despite the fact that she apparently didn't know it was Araragi on the other end...in front of several children. Moments later she interprets Araragi's request for help to mean she should strip, which she then starts to do.
- From Hitagi Crab, a Shout-Out to Death Note:
"Make a deal with a shinigami, see a naked girl. Best shinigami eyes ever."
- Near the end of Mayoi Snail:
Mayoi: (deadpan) Congratulations.
- In the first episode of the second season, Koyomi spends about two minutes saying how he won't molest Mayoi and how he even hates her (while stretching like a marathon runner no less)... and then hits her with a tackle that would make an NFL player cry with envy.
Koyomi: "HACHIKUJI!!! I'VE MISSED YOU!! I haven't seen you, so I thought you moved away!..."
- Don't forget about this little gem from Senjougahara:
Senjougahara: "You might not be able to tell with my clothes on, but surprisingly enough, my body isn't worth the jail time."
- This might be an example of Fridge Horror as if you recall that she was almost molested, it shows a darker meaning behind it.
- Pretty much everything Kanbaru does to Koyomi in Episode 2 of Nisemonogatari.
- Prior to that the panic Kanbaru shows when Araragi points out that she isn't very perverted, prompting her to go after him.
- In Episode 4 of Nisemonogatari Tsukihi walks in on Araragi in the bathtub... with Shinobunote sitting next to him. Tsukihi returns moments later with a knife.
- In Episode 5, Hanekawa gives Koyomi a "ticket" that allows him to touch her boobs as much as he wants, as long as he wants. Koyomi's pretty damn happy... until Hanekawa adds that she'd hate him forever if he used it. Koyomi immediately decides that it ain't worth it.
- In Episode 7, after taking Karen home, Koyomi ensures she won't go out again by writing "Any man will do" on her forehead in permanent marker. Then, just to be on the safe side (or possibly for lulz) he writes "Wearing a bra is a pain, so I'm not" on Tsukihi's cheek as well.
- In one fansub, Tsukihi's is "Disregard bras, acquire liberation."
- Episode 9 of Nisemonogatari. During an attempt to 'greet' Mayoi, Koyomi is tripped by Shinobu, who then proceeds to wave mockingly as her hand disappears back into his shadow.
- We find out in Nisemonogatari that Koyomi is afraid of heights by Karen carrying him around on her shoulders. It's also ridiculously cute. He even cries.
Koyomi: "S-s-s-s-scared! Scared! Scared! Scared! It's too high and very scary! Let me down. Let me down. Let me down now! I'm sorry! Please let me down, Karen-san! No, Karen-sama!"
- In Episode 10 of Nisemonogatari, while talking to him in Mr. Donut, Kaiki snatches Koyomi's wallet out of his hands and keeps the entire thing. He does not stop talking at all.
- Koyomi meeting young Hanekawa.
Young! Hanekawa: Are you...a pervert?!Koyomi: [A look of genuine horror]
- In the same vein, Shinobu getting hot and bothered over a young Koyomi.
- The usually stoic Ononoki getting distracted by Koyomi's muscles.
- Even though the ending of Onimonogatari completely ripped out your heart and throws it into the trash, the fact that Mayoi had climb up on Ononoki's shoulders just give Araragi a Last Kiss is a little funny.
- The opening for Hitagi End part 3 is done up in 90's shoujo anime style. Senjougahara and Kaiki with HUGE FREAKING EYES!!!
- "Senshougahara"'s glasses and "Suzuki"'s Hawaiian shirt.
- In Hanamonogatari, Kaiki is able to beat Kanbaru in a foot race. Mind you, Kanbaru has been doing track and field for years.
- From the end of Tsukimonogatari, Araragi returns home to see his two sisters partially undressed. But what really freezes him up is the sight of Yotsugi sitting in the house, pretending to be a doll.
