calling all doctor who fans: help, plz?

Does anyone know of any quotes or particular moments during New Who that showcase the Doctor's ability to be a self-righteous bastard Ubermensch characteristics? I found the whole "You want to take it to a higher authority? There isn't one," bit - which I think is from New Earth - but despite the fact that I know there are just a PLETHORA of examples out there, I can't seem to find any.

I swear, it's quite important.
