Dragon Ball Z, Season 1

Gohan:
Don't be silly mom.

Chi-Chi:
I'm silly? My son tells me I'm silly? I'm not the one who wants to run around and be a superhero.

Gohan:
Bulma, you'll take me with you, won't you?

Chi-Chi:
That's it. I'm putting my foot down Gohan! I won't let you leave me again. You just came home, after you've been gone for a whole year Gohan. You're a child. Act like one! Don't throw away your childhood trying so hard to be a brave adult. Being a kid's the best part of life. You should be making friends and playing baseball, not trying to save the world!

Gohan:
I'm going!!!

Chi-Chi:
H...How did I raise such a stubborn child!?

Gohan:
There's no time for those childish things anymore. My friends are gone and they're not coming back. I've got to help find the dragonballs. Mom, Piccolo died trying to help me so I think I should do everything I can to help him. I can't sit around and do nothing while Piccolo needs me. I'm sorry I yelled at you Mom, but I have to try. You see...they're my friends.

Yajirobe:
Heh heh heh heh. Pretty good speech kid. You sure didn't learn that from your father.
