Miley: Daddy, what if something goes wrong with the surgery, and I can't be Hannah Montana anymore?
Robbie: Well, I guess you'll have to pack your things and get out! (Pauses) Darlin', that's not gonna happen.
Miley: How do you know?
Robbie: 'Cause there's some things a daddy just knows. Like, I know the sun's gonna come up tomorrow. I know Uncle Earl's never gonna be an underwear model, and I know your voice is gonna be just fine.
