Krillin, Gohan and others in “Unfinished Business”

Krillin

[Bulma is holding baby Trunks] Heh, I hope you don't think I'm nuts for asking, but what's the deal with the baby Bulma?

Is it your son Yamcha? I'll bet he is.

Yamcha

Heh. He's not my kid.

Krillin

Huh?

Yamcha

Well, if you think that's a shock, just wait. Wait until she tells you who the father really is.

Krillin

Huh?

Uh?

Ha ha ha. I'll bet it's Vegeta, isn't it? [tapping baby Trunks] Right Trunks?

Krillin

Uhh?

Ehh?

Now who told you that Goku? I wanted to keep it a secret. I was going to surprise you guys.

[laughing from panic] Aha ha ha ha ha ha...well, actually...I just thought I'd take a guess. I mean, he kind o' looks like Vegeta. Aha ha ha ha ha ha...

You guessed his name too.

Yeah...what are the chances of that, huh? Maybe I'm psychic.
