I find Nya-kun's sig ironic.

I have no idea, but I'm assuming some character from a commercial/kid's TV show or something.

Suuuure you wouldn't.

What is the frog thing she is holding?

I wouldn't be caught dead with a photo of 14 year old. But 16 is pretty young, anyway.
She's from the Korean pop group Wonder Girls (Same group as a girl from my avatar ages ago, the short black-haired one).

16? I thought she was 14.

Who is she, by the way?

Oh she is, isn't she? Even though she's only 16, it doesn't make her any less attractive.
A bit of a scary thought. But mmm...

The girl in your sig is cute, and I don't care if she is underage.

That could work.

Or I could look here, I suppose?

You could always go look at the Music forum to find out. I post more there than anywhere else.
