This is an idea that randomly occured to me and made me laugh. Yeah, it's kinda random and cracky.

Sealand walk through the house looking for Uncle Denmark. All of the Nordics were over today and he was looking forward to spending sometime with his favorite Uncle.

On his way, he ended up finding Uncle Norway and Iceland (who was technically his uncle too, but since Sealand was his sempi, it felt too weird to call him that.) in the kitchen. Iceland was sitting at the table, angry glaring at the wood. Norway stood over him saying, "You promised. Now say it."

"No. It's stupid and childish."

"No its not. I'm your older brother and it makes me happy when you say it. Now call me 'onii-chan'."

"I will never say it."

"But it'll make us closer. Don't you want that?"

Sealand tuned out and didn't hear Iceland's response, but the conversation had sparked an idea in his head. Ladonia was his younger brother, right? And he wanted them to be closer. So, it was decided. He would get Ladonia to call him onii-chan!

He ran upstairs to Ladonia's room. Unsurprisingly, the internet nation was sitting at his desk on his computer with his headset on.

"Ladonia!" Sealand shouted and Ladonia jumped.

"Sorry, Estonia. I'll be right back. It seems Sealand decided now would be a good time to bother me." He said to the mic. Then he took his headset off and turned to glare at the other micronation. "What do you want, idiot?"

"You should call me onii-chan!" Sealand exclaimed.

"Why on Earth would I do that?"

"Because you're my younger brother, duh."

"I'm older than you." Ladonia said and stood up.

"Yeah right! I was born during World War II, you were born in 1996! I'm waaaaay older than you!"

"That's not how it works for nations!"

"Is too!"

"Then how is America older than Uncle Iceland?" Ladonia pointed out.

"Fine, its not. But I'm still older than you."

"Fine, but even if you were, I still wouldn't say it."

"Why not?" Sealand whined.

"Because you're not my brother."

"Am so!"

"Are not!"

"Am so!"

"Are not! We're not related at all."

"Not biologically. I'm adopted. But we're still brothers so you should still call me onii-chan."

"I highly doubt anyone one but you and Sweden find eBay to be a valid adoption site."

"Sweden's my dad and your dad so we're brothers." Sealand explained.

"Well, Sweden's not my dad, so ha!"

"Well then, what is he?"

"He's my brother. So, I'm your uncle, not your brother."

"How do you figure that?"

"Well, you declared you independence from England, right?"

"Yeah..." Sealand said, confused as to where this was going.

"And he's your brother, right?"

"Yeah, unfortunately."

"And I declared my independence from Sweden so he must be my brother." Ladonia reasoned.

"No, he's your dad." Sealand said stubbornly.

"No, he's not!"

"Yes he is!"

"Is not!"

"Is too!"

"Is not!"

"Is too!"

Ladonia looked back at his computer for a minute and realized he had left it alone too long and was about to be found out. "Shit! Out of my room, now!"

"Why?" Sealand asked. "What are you doing?"

"Me and Estonia are trying to hack into America's top secret government files." He sat back down and put his head set back on. "Estonia? I'm back! Sorry, I didn't realize how long it'd been."

"Why are you doing that?" Sealand questioned as he came closer.

"Because America was bragging that it was unhackable and dared us to. Now, GET OUT!" Ladonia quickly got up and pushed Sealand out of his room. Then he shut and locked the door.

"This isn't over!" Sealand called from outside. "You will call me onii-chan!"
