The entirety of the water fight scene. Especially when Haku pushed Zabuza into the water.
The "fight" between Kiba and Shikako in chapter 32.
And this little exchange in chapter 36 when Gaara lets the Ichibi, Shukaku out:
Temari: Only the Kazekage can deal with him when he's like this. Shikako: Hmm. We're fresh out of Kazekages. Shikamaru: Given the invasion, it probably wouldn't help even if we had one. Kiba: Yeah, I can imagine that. 'Ahem. Excuse me, Kazekage sir, could you please abandon the battle and come restrain your Jinchuriki? It seems to be getting out of hand. Much appreciated.' Sasuke: That's rather polite for you, Inuzuka. Not going to just demand help? Kiba: Well, y'know. Foreign Kage. Got to be on your best behaviour, right? Temari: You're all mad.
