Doctor Who: The Last Voyage

Sugar: We are going to die
Doctor: Sadly, yes, but not today

Sugar: Tell me you can drive this thing
Doctor: I can drive this thing
Sugar: Yeah, only tell me if it's actually true
Doctor: I do like your hat

Well, anyway, the real problem is, unless we regain control and begin to stir this thing we can go forever and i meand forever in a very infinite sense.
