Heavens, Grand Kai. You must be very excited to be giving your private lessons to either of these wonderfully skilled fighters.
[to himself] Oh, darn. I did make that little promise, didn't I? I was hopin' they wouldn't remember.
I've never fought someone quite as powerful as you are.
It's because you're strong. I find that my toughest opponents always bring out the best in me.
Well, this should be exciting then, since I'm about to get much tougher.
You got me.
And I'll finish you...using the special attack you seem so fond of.
[after Goku defeats Pikkon] You got me.
Well, Pikkon...it was a mistake to use your thunder flash move a third time. By then I'd seen the attack enough times to find a weakness in it.
Huh? Heh heh heh heh. I see. Truly, you're a great fighter. Enjoy your private lesson. I'll keep training and beat you at the very next chance.
Great. Hey, thanks for fighting with me.
We broke the rules so we lose. Hm.
But your fight rocked. So as a bonus, I'll allow both you and Pikkon to take my private lessons in two to three hundred years.
Two hundred years. Great! I'll be there!
[to himself] That'd give me just enough time to whip back into shape. I've been too much of a couch potato to keep up with those boys now.
