A/N: I tried to post it on Monday, but it didn't work. I also kind of bended the prompt rules. Meh, oh well. Prompt is at the bottom.

Disclaimer: I don't own anything! And because of this, the world keeps on spinning.

Monday

"Danny, I didn't expect you to be a sucker to marketer's mottos." The older Fenton watched in amusement as her brother shoved down the rest of his cereal. "Don't always believe what the box says."

"But it's magically delicious!" He exclaimed sarcastically, before choking on one of the marshmallows. Jazz couldn't help but laugh. Oh, the irony.

"Okay seriously, what's the rush?" Danny stopped packing his backpack.

"It's Monday," he exclaimed, like that explained everything. Jazz rolled her eyes.

"Obviously. I'm going to guess there's a test in first period. Speaking of which, did you do good on the last one?"

"It's well, not good. And here I thought I was the dumb one." Okay, so maybe he was pushing it. He didn't even know that until yesterday nor did he really care. But someone had to get her off her high horse. "Gosh Jazz, don't you know anything?"

He didn't notice the faint snap when he shut the door.

"Hey guys. Sorry I'm late." He stopped, wondering if he should run. Because Sam was smiling. Not a 'I-just-freed-a-spider-from-dissection' smile but the 'you-might-find-that-razor-I-lost-in-your-sandwich' type. Hesitantly, he asked why she was. She immediately frowned.

"Do you have a problem with it?"

"N-no! Nope, not at all!" He smiled nervously at her combat boots. "It's just uh, different? Different is good, right?"

If Sam heard the plea in his voice, she showed no sign of it. Instead, she started digging through her backpack.

"Danny," her voice dripped with aspartame, making him ignore the frantic "don't do it!" waving from Tucker. "I got a project for history and you're gonna help. Wear these for me, kay?"

She tossed something at him. Through the fog of his brain, he recognized they were clothes. Ninja clothes.

"Danny doesn't have history with you." Tucker reasoned, attempting to save his best friend one last time. The goth smirked.

"And that's why he's going to skip math so he can help. Right, Danny?" The ghost boy nodded immediately. No one could refuse those amethyst orbs.

"Thanks! See you in a few!" She kissed him on the cheek and walked off. Danny's hormones couldn't take it anymore. His nasal cavity exploded from pure overload and he fell to the ground, gasping like an idiot. Tuck shook his head in pity.

"Dude, you are so whipped."

The raven-hair teen wiped blood from his nose and smiled dreamily.

"It's worth it."

"Still worth it?"

"Shut up Tucker."

Danny hid behind a garbage bin, desperately trying to peel out of the costume. No such luck.

"What did Sam do to this; dip it in super glue?" The techno geek shrugged.

"No clue. But kudos for it being authentic. Oh look! It's even got those star thingies!"

He grabbed one and threw it in the air, where it passed through some bushes before implanting itself into the skull of Dan Phantom, who had just happened to escape his prison to wreak havoc on the past.

"Cut it out Tuck," Danny scowled, retrieving the ninja star from his former Ultimate enemy's corpse. "You could have killed somebody."

He put the weapon back.

"Okay, now to find Sam."

Blue wisped out of his mouth.

"Or maybe not. I'm going-ow!" Danny rubbed the spot where Tucker hit him.

"Dude, stay in character. Ninjas don't scream." Danny sighed.

"Fine." He threw down a smoke ball. When the smoke cleared, the local ghost hero stood in Fenton's place. Phantom looked down at his unusual attire.

"Seriously, what did Sam do to this costume?"

He had no time to find out because the ghosts emerged, screeching like the pigeons they used to be.

"Bread crumbs!"

The ghost boy dodged their pecks of doom and whipped out some nunchucks. Coating them with ectoplasm, he encircled them in his weapon and pulled out a thermos. But of course, he had to have at least one witty banter or pun.

"That's a wrap!"

He yelped when one of the pigeons pecked his hand and he dropped the thermos below. The ghost escaped and resumed attacking the ghost boy, who was busy trying to find his thermos. Finally annoyed, he cracked open a smoke ball and vanished.

While the ghost bird continued looking for 'bread crumb man,' Danny was below in the bushes. He heard footsteps behind him.

"Okay, where is that thermos? Hey Tuck, can you help me find it? Tuck?"

A hand grabbed him and in a matter of seconds, he was encased in a dome shaped ghost shield in the middle of the woods.

"Whose turn was it to annoy me this time," he growled, throwing his fist against the shield with little success. "Vlad? Val? My parents?"

"Jazz?" He looked up to meet teal eyes.

"That's me! Jazz. J-A-Z-Z. Jazz," she screeched, giggling like a two year old.

"I'm Jazz. Did you know that? I did!"

Oh-kaay. Something was downright trippy about his sister today, more than usual. She looked like she had just lost wrestling with a tree and every ten seconds she would spaz out something like, 'I know everything!'

"You feeling okay, Jazz?"

"Super. Magnificent. Jubilant," she squealed before smashing her face against the dome.

"NO! You said I was wrong! You said I didn't know anything! But guess what? You were WRONG!"

The way she barred her teeth made Danny so glad there was a barrier between them right now. From his vast dealings with fruitloops, it was time to take the safe approach.

"Umm...sorry? I was wrong to question your intelligence, and it will never happen again. I got class. Can you let me go now?"

"WRONG!" He fell flat on his butt from the rebuttal. When did Jazz take bipolar lessons from the Lunch Lady?

"You're wrong! You're going to stay here and listen to how smart I am." She opened up an encyclopedia. "A. The first letter in the Roman alphabet as used in English. I knew that. Did you know that Danny? Huh? Did you?"

Before Danny could reply, Sam and Tucker flew out with a thermos and a... coffee mug? Not going to ask about that one.

"Danny! What happened?"

"Jazz went cuckoo so she trapped me in here. Ya gotta get me out before she reads more of the encyclopedia!"

"You got booked by your sister?"

"Yes!"

His friends burst out laughing. The halfa rolled his eyes.

"Har har, very puny. Are ya'll gonna set me free or what?"

His friends didn't listen, too busy cracking book jokes. And Jazz wasn't stopping anytime soon.

"Did you get the joke Danny? I did. Huh? Did you? Did you?" Danny groaned and fell on the grass.

This was going to take a while.

A/N: Okay, here was the prompt.

Monday: Sam convinced Danny to wear a Ninja Outfit. Danny hid behind a bush, about to capture some ghosts. Then, a hand pulled him back and trapped him in a Ghost Proof dome. It was Jazz! Jazz gets Crazy Cuckoo because she was wrong. She reads Danny an encyclopedia. Will Danny survive? Will Sam and Tucker hold back their laughter?
