Chouji was just eating his favourite snack, minding his own business when Gai sauntered up to him.
"Chouji! What are you doing?"
"Just eating, Gai Sensei." Chouji replied uncertainly, unsure of where the conversation was going.
"I'm here to offer you something very valuable. This is a ONE TIME OFFER! And VERY VALUABLE! So, Chouji Akimichi, will you RISE TO THE CHALLENGE?! Will you TAKE UP MY OFFER?!"
"Umm... I can't take it up if I don't know what it is." Chouji said matter-of-factly, making Gai shake his head in annoyance.
"No matter, no matter. I wanted to offer you... THIS!" With a flourish, he pulled out a green spandex out of thin air.
"No thanks." Chouji said uninterested, turning back to munching on his snack.
Gai reeled backwards in shock. "BUT! This is a SPECIAL suit! It's breathable, and it clings perfectly to your form, it-"
"No really, Gai Sensei, I don't need it." Chouji said again.
Gai couldn't believe his ears. Maybe he should try a different tactic. "It can even help you to lose weight!"
Chouji's head snapped up, his voice low and dangerous.
"Gai Sensei. What did you just say?" he threatened.
"I said that this MAGICAL SUIT can help you to lose WEIGH-"
"I"M NOT FAT! I'M PLEASANTLY PLUMP!" Chouji all but screamed, launching himself at Gai. "PARTIAL EXPANSION JUTSU!" He yelled, making his feet large, stomping after Gai, trying to crush him.
Gai laughed hysterically as he ran away from the rampaging ninja. "Look what energy it has given you! If you put it on, think of the WONDERS it could do! It could-"
Gai was cut off when he was stomped on by Chouji.
"I DON'T NEED TO LOSE WEIGHT!" Chouji screamed again, then stalked away.
Gai just lay there, unable to move, wondering why Chouji was so oblivious to the wonders of spandex.
