Just Because We Both Have Silver Hair Doesn't Mean We Are The Same Person, Dobe

Summary: In which Sakata Gintoki suddenly found himself in Naruto world where everyone mistook him for Hatake Kakashi and vice versa.

Part 1: Can I Have Another Cup Of Coffee Because It Is A Weird Morning

It was a weird morning for Naruto, or rather it was Kakashi sensei who was acting weird that morning.

First of all, Kakashi sensei never showed up for Team Seven's training. When Naruto decided to look for his sensei, he found Kakashi walking on the street, reading that damned book. He did a double take.

When did Kakashi sensei perm his hair? What's with his half-ass clothes? What the hell? That crafty bastard!

"Hey, Kakashi sensei! Don't think that I can't recognize you now that you have perm hair…" Naruto slapped his sensei's shoulder from behind.

Naruto's jaw nearly dropped to the floor when the silver haired man turned around.

The silver haired man swallowed his last dango and replied, "Brat, you got the wrong guy. I am not your sensei."

"Gah, Kakashi sensei! You are NOT wearing a mask!"

This was the first time he has ever seen Kakashi sensei eating openly in public. No fish lips, no chipped teeth or any noticeable facial deformation. Just a plain looking guy with dead fish eyes. After all these years countless failed attempt to spy on his sensei, the man decided to reveal his face just like that. On top of that, the man has the nerve to pretend not knowing him!

"Why are you pretending that you don't know me? And why are you wearing those strange clothes and perm your hair?"

Then suddenly an idea hit him. There was only one explanation for this.

"I get it! You are disguising yourself in an undercover mission." Naruto tried to convince himself but something else was fundamentally wrong.

"Wait… why the hell are you in an undercover mission in your OWN village?"

The silver haired man already walked a few meters away.

"Hey, don't ignore me, Kakashi sensei!"

It was a weird morning for Gintoki, weird in the sense that he found himself woke up on a stranger's bed, in a stranger's room. His hangover was so bad that he couldn't remember how he got there in the first place.

He considered going back to sleep but his throat was burning. He dragged himself up grudgingly in search for a glass of water.

It was a small bedroom with no attached bathroom. From the looks of it, the room probably belongs to a guy. The furniture was scarce and although the room was relatively tidy for a guy's standard, it was probably due to how little time the guy spent in that room. Poor guy, he thought.

Maybe he was knocked out in the bar the night before and someone brought him home?

But he had absolutely no idea who the Samaritan was. Everyone who knew him would have brought him back to his Yoruzuya house.

Whatever. He could thank the guy later.

Or maybe not. He quickly checked his ass. No sign of forced entry. Phew, he let out a sigh of relief.

He poured himself a glass of water and downed it in one gulp.

His stomach was growling as well. Right, he probably threw up everything he ate the night before.

Gah, I need sugar!

He was ready to leave the room when a pocket size orange book on a shelve caught his attention. He picked up the book curiously. Icha Icha Paradise Ten Year Anniversary Limited Edition?

He flipped to the first page. To his pleasant surprise, it wasn't half bad compared to his favourite Jump magazine. Before he realized it, he was so engrossed in reading the Icha Icha novel that he paid no attention to his surrounding until someone slapped his shoulder from behind. He turned around and found a blond boy staring at him as if he saw a new species of Amanto standing in front of him.

"Gah, Kakashi sensei! You are NOT wearing a mask!"

Who is Kakashi sensei? Certainly not him. He is nobody's sensei.

"Brat, you got the wrong guy. I am not your sensei."

He finished his last dango and deliberately slipped the dango stick into the blond boy's pocket. Seriously, the boy was too loud. He ignored the boy's yelling and simply walked away.

Hm, where was I again? Ah, yes. The part where Akiko professes her undying love for Takuma and starts stripping off her kimono.

"Hey, don't ignore me, Kakashi sensei!"

Why does this annoying brat keep calling me scarecrow? Is that even a name?

And then something occurred to him. He had seen this brat somewhere before. Blue eyes, blond hair, hideous orange jacket…

Right, he saw this brat in one of the pictures at the stranger's apartment. The man who was patting the boy's head in the picture also happened to have silver hair. It would be safe to bet that masked man is Kakashi and the boy has mistaken him for that man.

It was all just one big misunderstanding.

"Look, I'll say this again. I'm NOT your Kakashi sensei."

The boy looked even more confused.

"You really don't recognize me? I'm Naruto, your Genin student."

"Naruto?"

The name definitely rang a bell. The Jump fan boy in him screamed in excitement when he recognized who the boy really is.

"Oh my god, you mean you're Naruto in Naruto? Can I have your autograph, please?"

The poor boy promptly fainted.

It was a weird morning for Kakashi because he woke up on a stranger's bed, at a stranger's house. The last thing he could remember was that he was in a solo mission, the enemies outnumbered him greatly and there was an explosion. He couldn't remember anything after the blast. Did someone saved him after that?

He reached into his pocket for a kunai and found none to his dismay. There was however a wooden katana at the corner of the room. He picked it up and approached the door cautiously.

He strained his ears to listen but there was no sound on the other side of the door.

He opened the door and examined the surrounding with his Sharingan. No Genjutsu which is a good thing. A giant white fur ball in the living room caught his eye. He tiptoed to it and to his surprise, he found that it was a dog, a very large dog even by a nin dog standard.

The dog seemed to notice his presence and opened its big innocent eyes.

What an adorable dog.

The dog lover in the copy nin couldn't resist but to touch the dog's fur.

The next thing Kakashi knew was that he was suddenly swallowed by darkness, literally.

It was a weird morning for Sadaharu because his master's head tasted weird.

A/N: Yes, I know the title is super long but that is because all Gintama episodes have long and silly titles.

Am I the only one who thinks Gintoki from Gintama and Kakashi from Naruto are very much alike? They both have silver hair, fought a war and survived, lost their comrades, deceptively laid back yet can be dead serious when necessary, have unhealthy habits, addicted to specific reading material...

This is the first time I'm writing a crossover fanfic and I'm having too much fun writing it. Hope that you have as much fun reading it too.
