You're a pretty crappy teacher if you can't deal with repeatin' yourself once or twice.

[Vegeta never asked to be a teacher, though, so if Firo were in the same situation he's probably be acting similarly.

He only made the bet under the impression that there was no way he could lose and he can't give in so quickly. He takes one look at the house and quickly shakes his head.]

You've gotta actually gimme some time to get it! How long does it usually take people to learn this stuff?

[He's expecting a figure like a few months just for getting the energy out; that has to be difficult for more people than just him! ...Right?]
