The Doctor: You know what? This is the biggest library in the universe. So where is everyone?
The Doctor: It's silent...
Donna Noble :The library?
The Doctor : The planet. The whole planet.
Donna Noble : Maybe it's a Sunday?
The Doctor: No, I never land on Sundays. Sundays are boring. *
*"No, nunca aterrizo en domingo. Los domingos son aburridos"
