Tweek crawled along the floor, Sharpie clenched tightly in his fist. "Quiet, like a ninja. Swift, like a cow." He mumbled.

Cartman snored loudly from his desk, completely unaware of what was about to happen. The class watched with interest, their teacher too caught up in the wonder of fractions to notice.

Stan grinned from his seat besides the fat ass as Tweek began to scribble happily. Childishly, he drew a large pair of glasses and a curling moustache, stopping to jab softy at his cheeks to make zits, before giving him a large beard that dripped to his neck. He finished up with a scene of a dinosaur battling a blob on his forehead. He scrawled the word RAWR above them and again on his upper lip.

"Mr. Tweak!" The teacher exclaimed. "What are you doing?" Half the class exploded into laughter while the others either took pictures or tried not to laugh. Cartman blinked, starting to wake up. Tweek froze at the base of the desk, marker hovering in the air.

"The fuck? Tweek? The hell do you want, Spaz?" He questioned, sitting up to rub at his cheeks, smearing the moles around. The rest of the class began to laugh along as well.

Cartman slowly processed the laughter and eyed the marker, taking a moment before it clicked together. "You didn't!" He roared in anger, glaring down at the quivering blonde.

"Umm…Ninja attack!" He screamed, throwing the marker into his eye before whirling around and running for safety behind his best friend Craig. Craig
snickered and gave Cartman a look, although the hostility was still apparent in his eyes.

Come get him, just try. The look read. I dare you. Needless to say, he didn't try. Needless to say, Ninja became everyone's new favorite game. Except for Cartman, he was usually the one being ninja'd. But who cares what Cartman thinks anyway? Because when you're a ninja, you live by only one rule and one rule only.

There is no foe that can't be vanquished by a sharpie.
