I Can Has ROFL Nyao? Or, The ROTFLMAO of the Catgirl

[deadpan29]

From Throw Shadows at You, an AtLA fic in which Mai is the avatar.
Azula captures Sokka:

"So. Who are you supposed to be?" A snap and a snarl- Azula almost grinned. The boy was halfway to snapping already, and she hadn't even done anything yet.

Azula smirked. "What, you don't recognise the family resemblance? She draped one hand over her eye, and growled. I must capture the Avatar to restore my honour."

The boy burst out laughing. He didn't stop for some time.

"-I can't -I can't br- can't breathe," he choked out, rocking back and forth so violently that it almost seemed he was going to overbalance and fall backwards to the floor.

Azula frowned. This was not exactly the reaction she had expected.

"Oh man," he breathed, when he finally got control of himself. "That was the funniest thing I've seen in years. Do it again."

Azula coloured. "You are mocking me. That is generally considered unwise." It was also, to be honest, almost completely unheard of.

"I'm serious!" he protested. "You're actually really good at that. You nailed that weird meld of Growling Avenger and Pouty Twelve-Year-Old that that guy's got going on."

Azula tried not to show how much that description amused her. Instead she showed how amused she was at something else. Besides, it was oddly nice to be complimented on something that had absolutely nothing to do with firebending, or military prowess.

"You don't even know his name?"

He shrugged, as well as he could while tied to a chair. "I'll admit, it's probably come up, but I wasn't really listening for it."

"It's Zuzu."

He abruptly laughed again. "Seriously? Zuzu?"

Azula sighed. "Well, if you want to get technical, it's Zuko, but he hates being called Zuzu. I used to call him that when we were- well, when we were children."

Sokka nodded, committing it to memory. "Alright. I'll mention you to him the next time he burns our camp down in the middle of the night."

"Please do. And try to remember his reaction. I'll want to know about it when we capture you again."

He also gets some relationship advice from Ty Lee in this period.  Later, the tables are turned and he returns the favor for Azula.

"You don't get it, do you? This is... this is completely ridiculous. I mean, at least I had an excuse, 'cause I mean Mai's kinda reserved plus I only met her last winter, but seriously? You haven't seen it? She is literally all over you. I mean you are practically wearing her as a hat."

Azula's glare could have punched through steel. "Explain yourself."

Sokka threw up his hands. "Okay, you know what? You didn't let me figure out Mai on my own, so I'm just gonna go ahead and spoil the ending. Your acrobat friend? Is clearly into you."

Azula blinked.

"I beg your pardon?"

Sokka dragged his hands slowly down his face. "You are so completely clueless. She digs you. She'd like to get to know you better. She wants to take higher than you've ever been. She wants to know what love is, and she wants you to show her. She wants to stand with you on a mountain, she wants to bathe with you in the sea. She wants you to tie her down and do sexy things to her. Is any of this getting through to you?"

No, I don't believe the world has gone mad.  In order for it to go mad it would need to have been sane at some point.
