Kirk, Dirk and others in “Unfinished Business”

[as Tiff enters the classroom] What are you doing here?

You got expelled from school.

And we did the expellin'.

I'm taking charge here and you're taking a hike. [Kirby, Tuff, and the Cappy kids are surprised]

You don't count so good for a math teacher.

It's three against one!

True... But I've got one brain and you three bullies haven't gotten any.

Then let's have a toughness test!

That's fine with me.
