A/N: Okay, people, I'm back! This is the third part in my "First Day" trilogy. The three chapters, starting from chapter 3, were concerning Naruto's first two days of school. The next chapter will probably be the first of a few time jumps toward Naruto's graduation from the Ninja Academy. Anyway, I finished my idea of the prank that Naruto is about to pull and it turned out better than I thought! Like Naruto said at the end of my last chapter, this is going to be fun. I like the response I'm getting for my story. I also like the positive response to me introducing Hinata so early into the game. I plan on using the entire rookie nine for something in this story; I just haven't thought about it much. Anyway, here are the review responses.

LoveDetermination: Really? I thought bringing her in too soon would kill the story. Thanks for the positive reinforcement. "Now that she's here, what can I do?" is my real concern right now. This chapter won't really focus on Hinata very much because I want to describe the prank in excruciating detail.

Dilandau-Baka: Be prepared to laugh really hard. I sure did when I read my chapter over.

Trenchcoatgirl-Kyo: Hmm, I think I'll keep things as they are with the normal teams, but with Hinata being a friend to Naruto. I can work with that a lot better. Sasuke can really make or break my story so far, even though Sasuke wasn't properly introduced yet. Thanks for the help! Also, don't worry, Iruka isn't hurt too badly.

Dragon Man 180: Actually, in my fic, it's both. Iruka doesn't actually help when he finds out. If anything, Iruka only rubbed salt in the wound as Naruto drowned in the embarrassment. Iruka is also Naruto's first target because Iruka is the closest target readily available and Naruto needs to test out his "'Prankster' brand stress-relieving system" on somebody. Also, don't worry Hinata and Naruto will get somewhat closer in the following chapters.

So, the conclusion of the "First Day" trilogy begins now. Enjoy the fifth installment of "Cheerfulness Incarnate"

(Last chapter…)

The bell rang as Naruto struggled with an especially hard word for a beginner. The instant the bell rang, Iruka ran to the door to block the way out as he gave the assignment. "A one-page summary; It's not like I'm going to do it. The way I see it, Iruka-sensei would probably accuse me of cheating if I did do it. I might as well start getting back at a few of the villagers. Speaking of which…" Naruto snuck silently behind his desk and rummaged through the drawers to see what he can work with. "Training kunai, some glue; an exploding tag and some weights; also, there is some odango he probably left over from lunch; this is going to be fun…"

(Start Chapter 5)

Naruto rushed as he tried to get everything ready. He had a little trouble activating the explosive tag since it needed a little chakra but Naruto managed to put a little bit into it as he moved a few things around. Naruto hid his wide grin as he scurried out of the room, passing a few children as he made it outside the door. He then peered into the room through a small space he made preventing the door from shutting. He suppressed his laughter as he waited for the fruits of his labor. The anticipation was almost too much to bear but he was able to keep it in while the inevitable events transpired.

(POV change)

Iruka sighed in relief as he approached his desk.

The desk was made of wood and had a central drawer, flanked by the legs of the table, three drawers attached to the side legs. His chair was also made of wood and had no cushion. The chairs legs were reinforced by beams attaching the four legs in a square. The legs also were reinforced by an "X" shape, created by attaching opposite legs by a supporting beam of wood.

Iruka sat at his desk, eating his odango as he graded the student's work. He was twirling his pen between two of his fingers when he dropped it. Iruka attempted to stand up in his chair to find that… he was stuck to the chair. The chair was also incredibly heavy for some reason. Iruka started to get annoyed as he struggled to get out of his chair.

(POV change)

Naruto's smile grew as he realized that the prank has begun and Iruka can't do anything about it. Naruto counted down the seconds before all hell broke loose.

"3…2…1…and NOW!"

Naruto's count was right on the money as the following sounds were heard throughout the academy building. A large explosion was heard as Iruka let out a large scream. A loud "Thunk" sound filled the air followed by a series of smaller "thunks" followed Iruka's scream. Two last sounds filled the air as Naruto fought to hold in his laughter. Another loud "thunk" was heard followed by an extremely loud and pain-filled groan from Iruka. Iruka said a small sentence that almost made Naruto lose it. Naruto, noticing approaching footsteps, immediately ran out of the building. He then collapsed into a fit of laughter as he stood up and jogged home, Naruto's laughter being heard across the village the entire time.

(POV change, a little earlier than the end of the last scene)

Iruka, who was suspended from the wall, immobile and in pain, was only able to say one thing. Even then, it was in pain-filled gasps.

"What…the hell…happened?" Iruka managed to say while unable to attempt to ease the pain from his… lower area.

Teachers rushed in a moment later to see a very amusing scene. Iruka was apparently glued to a chair while being suspended on the wall. An odango stick was embedded into the wall about 3 millimeters away from each of Iruka's ears. Iruka was obviously in a great deal of pain as he turned, with difficulty towards them.

Iruka's desk was in shambles. The desk seems to have exploded from the inside, spreading its contents across the room. The desk was burnt beyond repair, as was the surrounding floor area. Two sets of weights were also found in front of the ruined desk. A slightly-charred plastic plate was also on the floor, to the left of the scorched desk.

Iruka spoke to the teachers, who seemed to be trying, and failing, to hold in their laughter. "Well, are you going to help me, or not?" Iruka said through clenched teeth.

The teachers snapped out of their respective trances and started to help the enraged Iruka off the wall.

(The next day)

Iruka was still a little steamed about the predicament he was placed into yesterday. Who am I kidding; He was pissed! Iruka was also extremely confused about the whole deal. The proof was still there. The scorched desk had not been replaced and the floor was still charred. Remains of Iruka's clothes from yesterday could be seen on the chair if one were to look hard enough. If one were to look closely at the wall, the holes in which the kunai and odango sticks were stuck into still remained, mocking Iruka and reminding him of the incredibly embarrassing and painful experience.

The students filed in shortly afterward. There was not one who did not notice the charred remains of the educator's desk, but they did not question Iruka since they also noticed the anger rolling off Iruka, almost palpable. A few students figured that this was the result of an extremely funny prank with Iruka acting as the target. Those students either smirked or snickered under their desks, not wanting to get on Iruka's bad side today. Those students also did not know how right they were.

Naruto then walked into the room to find the remnants of his first prank on display for everyone to see. He was instantly reminded of last night's… events, and burst into laughter in front of the class. Iruka instantly became enraged as the "demon" was laughing about something he was positive no student saw.

Gears turned in Iruka's head as he thought of who could be the perpetrator of such a horrendous prank. "Naruto was among the last people out yesterday, but this prank was so well done. He couldn't have done it. But if he didn't do it, who did? The fact that he is laughing about it suggests something. Also, that damn fox is in him so he is the obvious choice. Even if he isn't the one, I'll punish him anyway." Iruka thought with an evil smile.

"Naruto?" Iruka said with both an evil tone and a glint I his eyes. "Can you come here, please?" Iruka led Naruto by the ear into the back room.

(POV change, in the classroom)

The class heard a very loud argument between Iruka and Naruto. From what they can tell, Naruto was telling Iruka that he was not the cause of the destruction of the desk and Iruka was yelling back saying he was the cause of it and Naruto was going to clean up the room for doing so. The heated discussion lasted about 5 minutes until the class heard a loud "smack" sound. Naruto emerged from the room with a very visible bump and Iruka stood close behind, his hand in a fist. Naruto only went back to his seat, glaring daggers at his sensei. He was also grumbling something about "stupid teacher,can't take a joke."The lesson began, most of the class believing Iruka in saying that Naruto blew up Iruka's desk and leaving it at that. Only a few people thought otherwise. Hinata believed Naruto in the sense that he did not do it. The more observant class members, Shino and Shikamaru knew Naruto did it, but they were confused about how Naruto could pull it off. They also noticed the various holes in the wall in the shape of Iruka's body so they figured that Iruka was pinned up there. They were also among the few that noticed the clothing remains on the chair. The two observant boys also figured that Iruka was glued to the chair. Also, Iruka was walking oddly, slightly limping, today which suggested an injury to something near the legs. The two boys thought exactly the same thing.

"Who is this Uzumaki Naruto?"
