- Taiga tumbling out of a locker in the first episode.
- Boing and boing... [shakes] and BOING!
- Eternal Circle of Transmigration!
- Kitamura: "Stand, bow, ...whatever"
- In Episode 8: "Whoa. Hair's showing" (In the Dub, "Hey. Pube alert"). And the rest of Taiga's strategy.
- Also in Episode 8, when the Chariots of Fire music starts playing.
- "I just saw something... black and fluffy..." "I-it was probably just the seaweed ghost!"
- The "shower scene" at Ami's beach villa.
- Taiga's campaign for student president. "I am going to take over this school, turn your high school memories into a sea of blood, and send you all to the m-m-m-morgue!" And her running mate? Ryuuji.
- Ryuuji is known in school as the 'Most Pitiful Guy Ever'. Why? In the Festival Episode where he runs for Taiga's sake, you know the one, where her Jerkass father didn't show up, he swore to make it up to Taiga and Minori (with whom he argued with) and tried to win. He tied with Minori, but apparently "didn't get the girl" in the eyes of the student body who don't know the reasons why he wanted to win. This doesn't last too long, though... because Kitamura gets the title next after attempting to confess to Student Body President Sumire and apparently "getting rejected" (she was to study abroad in America but she actually returned Kitamura's feelings). This does not dishearten Kitamura, who instead makes up a radio school broadcast program about talking about romance problems. This becomes a plot point in the story's latter half...
- When Taiga comes back from school after being suspended for fighting with Sumire, she is shocked when Kitamura suddenly lays himself flat on his face in front of her, which he explains to be "The ultimate form of prostration!" Even though he asks her never to use violence again, he is grateful that she cared so much about his feelings.
- Another, after the school festival, where he finds a picture of him running in the marathon, looking absolutely like a devil. To his embarrassment, Minori doesn't seem to mind the picture at all. The picture gets a Call Back in the PSP game when Ryuuji gets memory loss; he is actually TERRIFIED of the demon in the picture, who is actually him.
- Ryuuji's lampshaded reaction to the Starbucks knock-off: "How is this place not getting sued?"
- Ami mocks Taiga for still believing in Santa Claus, and Taiga responds by very sweetly and childishly saying she shouldn't say such things or Santa won't bring her anything. Ami drops the teasing and says now Taiga is just legitimately creeping her out.
- Kitamura's costume at the Christmas Party. Enough said. It gets a Call Back at the last episode where the class takes a picture with him wearing the same outfit.
- The recently-released OVA based off an extra short story, "Ben-to no Gokui", is a mix of Crowning Moment of Heartwarming and Crowning Moment of Funny, hands down. Especially the ending where Ami and Kitamura make Taiga awkwardly "spoon-feed" Ryuuji using her chopsticks like a girlfriend, much to Taiga and Ryuuji's embarrassment and to everyone else's amusement.
- The very last scene where Taiga headbutts Ryuuji when he confesses his love to her. It's nice to go out on a funny note after all the melodrama in the second half of the series.
- In the English dub of episode 11, Haruta's hammy shout of "LADIES AND GENTLEMEN!" to a group of guys in a locker room before announcing his idea for the culture festival is meet with a chorus of jeers, which includes this nicely delivered line:
Ya slurrin' your "g"s, gggenius.
What's a "Zentle?"
- In the original Japanese he shouts "LADIES AND ZENTLEMEN!" in Gratuitous English, prompting the question:
