Itachi gripped his fingers around the shiny, metallic pantry doorknob. It seemed to taunt him, grin at him, to dare him to open the pantry, to risk leaving the room dejected and deprived of what he so desperately hoped to find there. He took a deep breath and turned the knob, swinging the door open slowly and deliberately, but visibly flinching when it split the silence of the room with an eerie, unnerving creaking. He couldn't take the suspense much longer, and he thought his heart was about to explode from the anticipation. But when he entered the room and saw what was on the pantry shelf, his heart managed to beat all the faster.
There, leaning ever so slightly against the wall, was a half-closed bag, sealed at the top with a rubber clamp. A bag that, despite its warm, colorful design, seemed to radiate an ethereal, holy chill that seeped into his mind and automatically, unconsciously registered as an object of worship.
Itachi raced to the side of the bag, and as he threw the clamp over his back and across the room, he held the bag up to himself, reveling in its beauty. The rest of the Akatsuki were out for the day, except Kisame, who was in his room and would not pose a problem. Nobody would find out. Nobody would know the one true weakness of the elder Uchiha. Itachi sighed contentedly. He could finally enjoy his Sun Chips in peace.
Itachi grinned devilishly and tore his hand into the bag. But something was wrong. He couldn't feel anything. Where were they?! Where were the chips?! There was nothing in the bag but air and scarcely any crumbs, hidden away in the deep crevices of the bag…
And….ah, hold on, a piece of paper! Itachi ripped the paper out of the bag, scanning over the note quickly.
Dear Itachi-san,
I have eaten all your beloved Sun Chips. Consider this payback for not letting me buy the collector's edition of Finding Nemo when we were at Wal-Mart last Saturday.
-Love, Kisame
Itachi threw the bag and note aside angrily. He turned slowly and clenched his fists, the sharingan turning his eyes a bloody crimson red.
"That bastard ate MY Sun Chips!" Itachi yelled angrily, stalking murderously out of the pantry and slamming the door behind him.
Kisame bobbed his head and sang as he listened to the theme from Top Gun through his new headphones. It was about this time that the door to Kisame's room was obliterated by Itachi's Amaterasu. Kisame, as it turns out, spent the next 72 hours under Itachi's Tsukuyomi as a result of his little stunt.
