After Kakashi finished his own introduction, Sakura squealed about Sasuke, and Sasuke gave his pretentious badass speech, the man nodded to Naruto. "Your turn, urchin-head."
Naruto thought about it a moment. "I might be me, I might not. I might like some stuff, but then again that could be a lie. I may hate some things, but that might be a lie too. I have no hobbies... maybe."
At that point, Kakashi stared at him blankly, while the pink-haired girl screamed about 'stupid introductions' and Sasuke grunted something about 'dead last losers.' Then the sometimes cyclops did something that left all but Naruto staring in shock.
"FINALLY!" the man shouted excitedly, waving his arms violently. "I FINALLY GOT A STUDENT WHO ISN'T RETARDED!" He promptly appeared beside Naruto, sticking his arm around him in a friendly gesture only to freeze as a kunai pressed into his side. He blinked, then mumbled, "A kunai in the side?!"
Sure that Naruto was about to get a severe haranguing for threatening their teacher, they both nearly hit the ground face first in shock when the gray-haired man bellowed, "HELL YEAH!"
Turning to Sakura and Sasuke, Kakashi screamed right in their faces, "PINKY, ANGSTBITCH, FROM NOW ON YOUR GOAL IS TO BE AS MUCH LIKE NARUTO AS POSSIBLE!" When they, both of them, started complaining, loudly, he just shook his head irritably.
"Y'know what? Fuck it. You both fail. The only one of you worth being a ninja is him," Kakashi was practically drooling at finding a new genin who wasn't a moron.
"WHAT THE HELL?!" Sakura roared angrily. "That's not fair! How did the class idiot prove he was worth being a ninja by giving stupid answers and trying to stab you?!" Sasuke grunted his silent agreement to all of Sakura's points.
"Because he realized what my answers showed, and then he even one upped me!" As Sasuke and Sakura blinked dumbly, he realized they still weren't going to get it. "A ninja doesn't give out information about themselves, you idiots!
"If you know what my favorite food is, then you know something I'm likely to eat and can try to kill me by poisoning it. If you know what I hate to do, you know somewhere it would be a waste of time to look for me if you're trying to track me down! If you know what one of my hobbies is, you can set a trap for me at a place I'm likely to do that! If you know my name, then you have a method of gaining information about me!"
He glanced toward Naruto, who's entire face and head was now completely covered by an orange and silver mask that was seemingly pulled from nowhere. Not a single blonde hair was showing, not a fraction of blue eye, and not an iota of pale skin. Kakashi jerked back in shock.
"UWAAAA! HE IS THE PERFECT STUDENT! GET THE HELL OUT OF MY SIGHT, I HAVE A SUPERNINJA TO TRAIN!" Kakashi shouted, before promptly shoving Sakura and Sasuke off the roof in his hurry to begin training his new apprentice.
Several months later, Orochimaru was prancing around the Forest of Death. "Sasuke-kun! Oh Sasuke-kun! Come out, come out, whereever you are!" Several hours later, he gave up. It wasn't until he finally spoke with Kabuto that he found out that Uchiha Sasuke had been forced to retake his last year in the academy along with his other potential teammate, Haruno Sakura.
Sighing, the snake sennin grunted. "Well, that was a dead end waste of time if there ever was one," he muttered. Glancing around, he shrugged helpelessly. "Maybe I should look into those rumors that Mikoto had an illegitimate daughter."
"NOT ANOTHER FEMALE BODY!" Kabuto whined plaintively. When Orochimaru just smiled brightly, the man sighed. "Will you at least stop trying to seduce Yondaime-lookalikes, just so you can tell them you're really a 'man' as a form of revenge?" Orochimaru smiled even wider. "Fuck it, I quit."
"Oh, Kabuto-kun! Come back! You know you think it's funny!"
"Get the hell away from me, you freak!"
"Aw, come on! I'll let you have that dancer girl you like so much!" Kabuto froze, glanced back, then kept walking as he muttered about how he didn't need her after she'd been used for a sacrifice. Orochimaru quickly added, "I'll even leave this one alive!"
Sighing, Kabuto slumped and turned back toward Orochimaru like a puppy to its master.
"I WIN AGAIN!"
About three years later, Naruto smiled as he leaned back in bed. He'd just finished having his way with Uchiha Sasuke's older sister, who was seriously twisted... in a good way. For the first time since he came back in time, he was actually exhausted.
About that time, the woman leaned over and whispered in his ear, "I'm really Orochimaru of Konoha's Legendary Sannin. I'm really a man."
Naruto looked down and met the suddenly snake-like eyes staring back at him from the Uchiha woman's face. Then he reached under the covers for a moment, causing the woman to let out a loud squeak of shock.
"If you're a man, I'm a turtle," he said with a nod. Then Naruto smiled evilly, as he added, "Again?"
For the first time, Orochimaru's plan had backfired, in possibly the worst way. Two days later, Orochimaru-chan crawled from her room looking half-dead. Kabuto just laughed his ass off, all the while thinking it served her right.
