Goku: Darn it! I told you this was impossible! Look, if we don't do something soon, we'll be history! Along with this whole planet.
Vegeta: Why do I care?
Goku: Wake up! Majin Buu's eaten everyone we care about! Everyone is gone! Even Bulma! They've become a part of Buu! They can't even die! I just thought, the least we could do, is put out old differences aside, just this once, and really work together. We owe that to our team mates! Our families Vegeta! Our friends! Look, you've always talked about our Saiyan race, how were the last of a mighty people. Well, it's time we accept we're starting a new race! One that can be just as strong, just as proud. But not if we're caught up in so many of out birthrights, to see what we have right in front of us! We've lost out old race Vegeta! Let's not lose this one too.
Vegeta: Kakarot, how do you know this fusion will be enough to stop him?
Goku: I don't know for sure, but I know it's the best chance we have for saving the Earth.
Buu: You two have lived long enough!
Vegeta: Here. Give it to me. What are you waiting for? Give it now!
Goku: You bet!
Buu: It's time to die!
Vegeta: C'mon. You said right ear, right?
Goku: That's right Vegeta. And one more thing: once we join our bodies, we'll be stuck in that form.. forever.
Vegeta: ARG! Imbecile! You tell me now? Don't you think that's important information?
Buu: To the end of Earth!
Vegeta: Alright, it's on!
Goku: Great! Thanks, Vegeta.
Vegetto: All right!
