Nappa: [about Goku] Vegeta, what does the scouter say about his power level?
Vegeta: [removes his scouter and crushes it] It's over *9000*!
Nappa: What? 9000? There's no way that could be right, can it?
Goku: I think it's right. After all, I was trained in the art of Kaio-ken.
Vegeta: Huh, Kaio-ken?
Nappa: [Charges at Goku] Why you little...! You're no match for me! I don't care how much you've learned!
