Vegeta and Cell in “Unfinished Business”

Vegeta

Don't tell me you're satisfied swatting flies like him. Heh. Guess a guy like you needs any victory he can get. From the way you've been carrying on, I was expecting a true challenge. If that's your idea of perfect, I might as well go home.

Cell

I'm sorry to hear that. I was hoping you'd stay. Destroying you would be a decent warmup.

Vegeta

Uh? Alright, but this time don't whine when I beat you.

Cell

I won't.
