- Chiaki's negotiations with the raincloud in the Beach Episode. The best part is when Kana shouts that she hates the rain and wants it to go away. IMMEDIATELY the sky starts to get dark again, until Chiaki appeases it once more.
- Just about every time Sensei and Ninomiya-kun comes on. Especially the video game, which is probably one of the funniest parts of the series.
- Haruka helping Mako-chan buy a bra.
- Also, Kana injuring herself while chewing gum. And the subsequent Training Montage as Chiaki tries to teach her to blow a bubble properly... and then Haruka inadvertently one-upping both of them afterward.
- Third season has Natsuki's attempt at a proper request to get Touma to come home earlier. With ridiculous results.
- Minori Chihara singing Keikenchi Sokujoujou. In character.
- Episode 6 of season 4. Makoto goes to the beach with the girls as Mako-chan... and ends up with tanlines from his swimsuit.
