This one made me really laugh. I believe it is a parody of a Reagan quote.
There is something eminently laughable about the dichotomy of the Paladin. They are agents of goodness and lawfulness by training, but they --like all mortals-- are not perfect. To the Paladin, this lack of perfection is sometimes ignored. One of the best examples of the story of a stereotypical Paladin "in game" is in Order of the Stick in the form of Miko Miyazaki. Though she was a side character, her arrival and eventual downfall seems a grand story unto itself.
