Bulma and Gohan in “Unfinished Business”

So I heard that you're going to take part in the world martial arts championship.

Yeah.

Wow. Well, I must say I'm a little surprised, Gohan. It's not like you have to prove yourself or anything.

I know. But Videl Satan discovered my secret. She's blackmailing me into it.

Again? Good grief, Gohan. You get blackmailed more than a politician. What is it with you and all these girls?
