Chichi quotes from Dragon Ball (by release date)

Piccolo: Five pure-hearted Saiyans? Impossible. Gohan and Goten are the only two like that.
Bulma: How rude of you! Vegeta may be a lost cause, but Trunks certainly has a pure heart!
Piccolo: Someone who has a girlfriend at that age is impure.
Bulma: Whoa! What era do you live in, old man?! Aren't you just being jealous?
Chi-Chi: That's right, Piccolo! Are you saying Goku is impure as well?!
Żółwi Pustelnik: It's true that he's kind, but whether or not a kind idiot who's obsessed with fighting counts as being pure-hearted is debatable.

Chichi: You're strong and you work too? How great is that?! You are a true man!

Chichi: What's happened, Goku? You only ate half of what you usually eat!
Goten: Father, is something wrong?
Goku: I just don't have an appetite.
Chichi: Do you have a fever?
Goku: I don't have a fever.
Chichi: Then, are you gonna die?
Goku: I've died about two times already but this time doesn't feel like dying.
