River Song: Use the stabilizers!
The Doctor: It doesn’t have stabilizers!
River Song: The blue switches! !
The Doctor: The blue ones don’t do anything, they’re just… blue!
River Song: Yes they’re blue: they’re the blue stabilizers! [presses the button and the TARDIS indeed stabilizes] See?
The Doctor: Yeah? Well, it’s boring now, isn’t it? They’re boring-ers! They’re blue… boring-ers!
Amy: Doctor, how come she can fly the TARDIS?
The Doctor: You call that flying the TARDIS? [scoffs] Ha!
River Song: Okay, I’ve mapped the probability vectors, done a fold back on the temporal isometrics, charted the ship to its destination and… [presses a button, the cloister bell clangs] parked us right alongside.
The Doctor: Parked us? But we haven’t landed!
River Song: Of course we’ve landed; I just landed her.
The Doctor: But it didn’t make the noise.
River Song: What noise?
The Doctor: You know, the… [does an impression of the TARDIS materialization sound]
River Song: It’s not supposed to make that noise. You leave the brakes on.
The Doctor: Yes, well, it’s a brilliant noise. I love that noise.
