Dragon Ball Z, Season 1

Raditz:
(to himself) How could that little brat's attack weaken me so much!? (to Goku) Kakarot, you're a fool! How do you expect to dodge that beam and hold me at the same time?

Goku:
You're right! I can't! We'll both go!

Raditz:
What!? That's insane! You'll be killed. Is that what you want?

Goku:
If its the only way for me to beat you!

Piccolo:
Hold on Goku, I'm almost ready! (to himself) So, you're going to sacrifice yourself? Goku...how very noble of you. And how convenient for me. Then again, even if I do kill you, it's only a matter of time before your friends wish you back with the dragonballs...too bad.
