Korin and Goku in “Unfinished Business”

[Goku is eating a lot] I don't wanna rush you, Goku. But aren't you forgetting something? Don't they need you? Back on Earth?

[eating] Yeah, I know. But it's just that they don't have good food like this at Grand Kai's place. This is delicious!

Yes, but you came here for senzu beans, not to stuff your face...
