One of my favorites.

"Have you ever heard of Plato? Aristotle? Socrates?"

"Yes."

"Morons."

One of the best lines from the movie, it can be used to succinctly illustrate the mindset of the average dissenting Catholic (such as myself, a few years ago):
"Ever heard of Thomas Aquinas? Augustine? Ignatius of Loyola?"
"Yes."
"Morons."

The great movie "The Princess Bride", featuring devilishly handsome Roman Catholic Cary Elwes, who played the young Pope John Paul II in the movie which featured Jon Voight as the old John Paul II.
One of the greatest movies ever. Hilarious script, fine acting, beautiful scenery - A+!
