Argyria

"Hey Kisame, do you know what Agyria is?"

"A type of algae, why?"

"Nope! Agyria is sliver poisoning that causes the skin to turn into a bluish or gray color, when exposed to light."

"Where do you learn this stuff from?"

"From watching movies, but that's not the point."

"?"

"Did your skin turn blue from silver poisoning?"

"Neko I'll give you credit for trying, but is that really any of your business?"

"None really, but I'm just really bored of trying to imagine Itachi do the Waka Waka."

"Wait, what?"

"I said 'you should not tell Itachi, that there is no way he could do the Waka Waka'."

"Why would I- Oh hey Itachi."

"What was it that I couldn't do Kisame?"

"I was just telling Neko that-, hey where did she go?"

"Don't make me repeat myself Kisame. What was it that I couldn't do?"

"Calm down Itachi and- what's the knife for Itachi? Itachi! AAAGHHHH!"

'I knew it! Kisame is warm blooded, not cold blooded.' "Kisame wake up, Itachi is gone now. You're in the medical ward, Kisame?"

"I hate you sometimes Neko."
