as serious as a animal crossing npc can be
AAAAAAARGH!
What?  What's in your head?
You think I wouldn't notice?
You think I'd let it slide?
NOT LIKELY, PUNK!
MY AVATAR IS SERIOUS! SERIOUS!
What don't you understand?  AAAARGH!
Whoa...
I think I screamed too hard there...
Talk about a head rush, everythin's sparkly...
YOU!  You're a real piece of work, you know that, kid?
What is it you're tryin' to do to me here?
Don't you know I got high blood pressure and chronic tunnel toe?
My doc tells me I gotta take it easy, try not to get too worked up.
Do I LOOK not worked up?  No!
All this chasin' you around's gonna do me in.
You're doin' this on purpose, ain't you?  Yeah!
You're enjoyin' this!  AARGH!
Why don'tcha just toilet-paper my cave while you're at it, you little punk!
MY AVATAR IS VERY SERIOUS!
