Botan, Koenma and others in “Unfinished Business”

Botan

This is Yusuke Urameshi, and he's honored to meet you.

Koenma

Mm-hmm.

Botan

[hitting Yusuke] Hey, are you trying to make me look stupid? Tell him how honored you are!

[laughing] That's a good one, Botan, but let's be serious, okay?

Botan

Why would I lie about something like this, you moron?

[still laughing, pointing at Koenma] Why would the Spirit World be run by a toddler?

Botan

[slapping Yusuke's hand] Don't point your finger at him!

And to think I was scared of the mighty King Yama!

Koenma

[clearing his throat] Well to be more exact, I am the mighty Koenma, and I am the son of King Yama. Even though I appear to be a child, I have been around over fifty times longer than you have, so watch your mouth when you speak to me.

So it takes hundreds of years to move past a diaper?

Botan

[punching Yusuke in the head] Can't you show an ounce of decency?!

Koenma

Actually, I'm proud to say that in addition to knowing the greatest secrets of the universe, I am also quite potty-trained.
