"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!" Patch by Jenni's Prints from Sweden.
