Sunset: And this is our fans.  
Adagio: Wait…fans?  
Sunset: Yeah, through this fourth wall, Pinkie told me about it.  
Sonata: Yay! We have fans!  
Aria: That sounds really dumb…

Sunset: That’s the Science Lab!  
Aria: I DON’T CARE.

I did forget to take into account spiteful mockery, yeah. I was thinking genuine amusement that wasn’t based on mockery–y’know, less “man, what an idiot!” more “You’re a funny guy; I think I’ll kill you last”, myself. It’s easy to earn spiteful amusement from a siren; quite a different beast to earn genuine amusement.
 
I imagine doing spiteful/evil things to other people would probably earn that. Just don’t be a putz while doing it and you should be fine.

I’d imagine if something bad ever happened to someone, Aria would be laughing so hard, she’d be crying. And knowing Adagio, she would be getting a kick out of it too.

@Mrmildock  
She rarely ever is. You know you’re doing something right if she is amused, because something like that doesn’t come everyday.

Aria is not amused.

Ooooh… :P
 

You can just tell that Sonny is daydreaming about the school’s “Taco Tuesday” here, can’t you? ;D
