When Naruto flashes back to the bell training exercise, Sakura is shown with short hair, but she hadn't cut her hair yet.
After Naruto fixes the bells and we see Kurenai, Asuma, and Gai with an unconscious Kakashi, Kakashi's mask is off for a split second.
When Kakashi tells Naruto to gather Chakra to his hand during the flashback, his neck is skin colored instead of the mask color.
When Jiraya tells Naruto he was trained by the Third Hokage, the red stripes under his eyes are gone. Then they reappear when he says The Third was strict.
Naruto: (Going to answer a knock at the door) What now? Are you telling me she dumped you already?
Jiraiya: Here's the room key. I want you to go right up to the room, train for a little, work on your chakra, and then go to bed. Okay? Ha ha!
Naruto: What?! So I suppose you're going to tell me it's time for the grownups to play now. Is that the vibe here, you big perv?
Kisame: I'm pretty sure you could go toe to toe with him, but I'm not sure I could. He's on a whole 'nother level.
Itachi: Yeah, if we faced each other, both of us would get killed. A rather unappealing outcome.
Sasuke: Naruto just keeps getting stronger and stronger. Compared to him, I...
Sasuke: Naruto fought tooth and nail to save you, Sakura. He displayed a kind of strength he'd never shown before.
Sakura: Naruto...rescued me?
Naruto: Gah, no! I just stepped in dog doo!
Naruto: Come on, come on, come on! Why did you choose me?
Jiraiya: Well the truth is, kid, a long time ago the Fourth Hokage used to be a disciple of mine.
Jiraiya: And you bear such a striking resemblance to the Fourth that it's almost laughable. That's the only reason.
Naruto: Hey, hey! Wait a second, Pervy Sage!
Jiraiya: Look, kid, I told you already, it's Jiraiya. Come on.
Jiraiya: The Toad Sage is only my cover. Allow me to reveal my true identity. From the north to the south, from the east to the west, not even the spirits can defeat this Sannin. The White Maned Toad Charmer, a red hot ninja who strikes fear in the hearts of men, Master Jiraiya. Yes, I'm speaking of none other but myself. (Laughs)
Naruto: (Sarcastically) Uh huh.
(after Jiraiya fails the bell test)
Young Tsunade: Well, Jiraiya. It seems I've won our little wager! (acting smugged) Enjoy your time on the stump.
Young Jiraiya: (groans annoyingly) Oh, shut up! You annoying little troll!
Young Tsunade: (grabs him by his shirt; enraged) What'd you say!? You smarmy little dork!!
(starts beating at him)
Sarutobi: Okay, that's enough, Tsunade!
Jiraiya: I wish you would stop calling me "Pervy Sage". I'm really amazing.
Naruto: What? An amazing perv?
Sarutobi: I don't even want to know where you are with your transparency jutsu.
Young Jiraiya: I haven't been caught peeping yet! The transparency jutsu is flawless! I swear!
Sarutobi: All right then. If you're so sure of yourself... (Glances elsewhere) Then I should probably tag along next time...
Young Jiraiya: (Pauses a moment) Wow, Sarutobi-sensei... You're a perv!
Jiraiya: Stop calling me Peverted Hermit! You have no idea what a great person I am.
Naruto: What? A great Peverted Hermit?
Sasuke: Why's Kakashi asleep? And why are all of the jounins gathered here? What happened?
Gai: Nothing much happened.
(Another ninja enters the room.)
Ninja: Is it true that the Itachi came back? And that he's after Naruto?
(Sasuke's eyes widen in rage)
Sasuke: It wasn't me. Naruto was the one that saved you from the Sand.
Sakura: Oh Sasuke, you're being modest...
Sasuke: He did. He fought with all of his heart and strength to save you.

Kanji Episode Title: おお、のォ～っ！自来也の女難、ナルトの災難
In this episode, the infamous "crow" makes its debut during the awkward silence after Jiraiya informs Naruto about how he is a Legendary Sannin. This crow will make several more appearances in future episodes.
In this episode, we learn from Jiraiya's stories that Orochimaru, Jiraiya, and Tsunade were trained by the Third Hokage, and that Jiraiya trained the Fourth Hokage. We also learn, by looking at the quick pan over shot of Kakashi's room and looking at the quick glimpse at the pictures, that Kakashi was trained by the Fourth Hokage. This also explaines how the "training with the bells" got passed down to Kakashi.
In the manga, Sakura says afterward that Sasuke must've been the one that saved her because only the Chidori would be strong enough to beat Gaara. But in the anime she doesn't say anything and appears to believe him.
Sakura learns from Sasuke that it was Naruto who saved her from Gaara.
Young Tsunade's temper over Young Jiraiya mirrors that of another Viz Media dubbed anime series, Zatch Bell!, where Tia always throws a fit if Zatch insults her by accident, or on purpose.
