A/N Kid Flash can't resist a challenge. And when a certain Meister of música steps in, well, let's just see where that takes us XD of, and btw,italics is singing

"Hey Kid Mouth" Artemis greeted
"Hey, Artepits" he snarked
"Hey Kid, guess what" Artemis said
"What?" he asked
"Anything you can do, I can do better" she grinned
"Ha!" KF laughed
"I can do anything better than you"
"No, you can't"
"Yes I can"
"No, you can't."
"Yes I can"
"No, you can't."
"Yes, I can, Yes, I can!"
"Anything you can be, I can be greater. Sooner or later,I'm greater than you" KF sung
"No, you're not" Artemis shook her head
"Yes I am"
"No, you're not"
"Yes I am"
No you're NOT!"
"Yes, I am. Yes, I am! I can shoot a perdiz With a single cartridge"
"I can get a sparrow, With a bow and arrow"
"I can live on pão and cheese" KF smirked
"And only on that?"
"Yup"
"So can a rat" Artemis sneered
"Any note you can reach,I can go higher"
"I can sing anything Higher than you"
"No, you can't" KF sings at normal level
"Yes I can" Artemis sings 1 notch higher.
"No, you can't" Higher
"Yes, I can" Higher
"No, you can't" Higher
"Yes, I can" Higher
"No, you can't" Higher
"Yes, I can" Higher
"No, you can't" Higher
"Yes, I CAN!" Artemis sings as high as possible, which is surprisingly high.

***** Else where in the mountain*******

Black Canary hears Artemis's high cantar and nods in aproval

*******back to Artemis and KF***********
"How do you sing that high?" KF asked in astonishment
"I'm a girl" Artemis growled
"Really?" KF laughed, receiving a soco from Artemis.
"Anything you can say I can say softer " KF brags
"I can say anything Softer than you. "
"No, you can't. " KF sings softly
"Yes, I can. " Softer
"No, you can't. " Softer
"Yes, I can. " Softer
"No, you can't. " Softer
"Yes, I can. " Softer "YES, I CAN!" Artemis Yells
"I can drink my liquor Faster than a flicker."
"I can drink it quicker, And get even sicker!"
"I can open any safe."
"Without bein' caught?"
"Sure."
"That's what I thought--you crook!" Artemis smirked victoriously
"Any note you can hold I can hold longer" KF sneered
"I can hold any note Longer than you."
"No, you can't."
"Yes, I can "
"No, you can't."
"Yes, I can "
"No, you can't."
"Yes, I can"
"Yes, I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I can"
"Yes you can!" KF agree's "Where do you keep all that air?" Artemis falls on sofá from lightheaded-ness.
"Oh" looks around then backs away.

*******later(once Artemis wakes up)***************
A/N btw, KF isn't using his powers in this part. Just thought I'd add that in here

"Anything you say I can say faster"
"I can say anything Faster than you"
"No, you can't" KF said quickly
"Yes, I can." Faster
"No, you can't." Faster
"Yes, I can." Faster
"Noyoucan't." Faster
"YesIcan!" Fastest
"I can jump a hurdle." KF bragged
"I can wear a girdle." Artemis pointed out
"I can knit a sweater."
"I can fill it better!"
"I can do most anything!"
"Can you bake a pie?"Artemis asked
"No." Wally admitted
"Neither can I." Artemis sighed

************************************

"Anything you can sing I can sing sweeter"
"I can sing anything Sweeter than you"
"No, you can't" Wally sung Sweetly
"Yes, I can." Sweeter
"No, you can't." Sweeter
"Yes, I can." Sweeter
"No, you can't." Sweeter
"Yes, I can." Sweeter
"No, you can't, can't, can't!" Wally argued
"Yes, I can, can, can!" Artemis retaliated
"Yes, I can!" Artemis sung
"No, you can't!" KF sung at the same time. Both collapsed on the sofá afterwards.
"Wanna get Megan to bake a pie?" Artemis suggested
"Aw yee" Wally nodded, imitating Pauly D from Jersey costa (A/N DONT ASK!)

The End
