A/N: I forgot to keep saying that requests for specific challenges are always welcome. I may not get to all of them, but feel free to send me them, and I'll try. This goes for all future chapters as well, in case I forget again. This chapter's challenge was a request from Woodlandfairykirk.

Disclaimer: I do not own Gai, Kakashi, Naruto, Sasuke, Sakura, Tenten, Neji, Lee, Konoha... you get the picture.

"I have come up with a magnificent, youthful challenge!" Gai crowed.

Kakashi didn't look up from his ever-present book.

"Did you hear, my most youthful rival?"

"I heard you the first time."

"The challenge is this: You must be me for the day, and I must be you, without a henge!"

"How is this competition to be judged?" Kakashi asked, hoping that Gai would have no answer and have to pick a different challenge.

"Hmm." Gai rubbed his chin in thought.

Kakashi had to stifle a laugh at the picture of Gai, lost in thought. I wonder if his mind will ever find its way back?

"Ah! I have it!"

Kakashi raised an eyebrow, not deigning to vocalize a response.

"We will ask every person we encounter to rate our performance from one to ten!"

Kakashi sighed.

"Now, I must get you a youthful green jumpsuit, and you must get me a mask!"

Sigh. Was it too much to ask to be left to read Icha Icha in peace? Apparently.

Kakashi leapt out in front of his team, dressed in a green bodysuit, complete with orange legwarmers, and flashed a brilliant smile while holding his thumb up. "I am Maito Gai, Konoha's noble blue beast!"

Naruto doubled over in laughter.

Sakura leapt into the air, screaming for Sasuke to defend her.

Sasuke glowered, eye twitching.

When they got hold of themselves once again, they had one question: "Why don't you take off your mask if you're Gai?"

Kakashi glared. There was no way he was going to take off his mask after all these years just because of a stupid challenge.

Elsewhere in Konoha:

"I wonder where Gai-sensei is?" Tenten murmured to Neji. "He's never late."

Neji stared off into space, showing no sign that he heard his teammate's musings.

Gai dropped down from the tree next to them, a mask stretched over half his face, his hitai ate fallen over one eye, a grey wig perched at a strange angle upon his head, and a book in his hand.

Neji's eye twitched.

"Gai-sensei! What a youthful expression of Kakashi-san!" lee crowed.

Tenten stared in confusion. "Are you really supposed to be Kakashi?"

"I am the copy-nin, Kakashi Hatake!"

"But, your wig is curly, you're shouting, and the book you're reading is Great Battle Tactics, not Icha Icha."

"Icha Icha is not as youthful a book as Great Battle Tactics!"

Tenten rolled her eyes.

"So how would you rate my performance as Kakashi?"

Gai trooped back to the meeting place, looking dejected. Kakashi, was as ever: late.

When he finally showed up, Gai greeted him. "Ah, Kakashi, how did your students rate you?"

"They gave me a three. They were very harsh with the grading when I wouldn't take my mask off. How about you?"

"Lee gave me a nine, but Neji and Tenten both gave me a zero."

"So we tied, again."

"Great!" Kakashi sped off to get rid of the ridiculous green bodysuit. There was no way he was wearing that for one second longer than he had to.
