Its Vegeta and Bulma!!!
I always liked them as a couple, though I don't know what got them together in the first place (and I doubt it was the one night stand)
Either way, they made a hell of a lot more sense than ChiChi and Goku. NOW that couple I can't even fathom how they got together...maybe ChiChi constantly hid pork buns around the house....
Dragonball Z characters obviously belong to Toriyama
