When they made this particular hero, they didn't give him a gun, they gave him a screwdriver to fix things. They didn't give him a tank or a warship or an x-wing fighter, they gave him a call box from which you can call for help.

And that's an extraordinary thing; there will never come a time when we don't need a hero like the Doctor
