Larry the Vatican II guy explains the new translation of the Mass, the nature of conscience, and the Novus Ordo. The instruction (delivered by his guest) is helpful too, though the jokes are sometimes a little harsh. Here, for example, from the second one (though the jokes lose a little without the sound and the context):
Larry: Now as everyone knows Vatican II was a new Pentecost.
Guest: What was wrong with the first one?
Larry: It was pre-conciliar.
Larry: Today we’re going to discuss how Vatican II corrected centuries of error by teaching us that we can now follow our conscience.
Guest: We were always able to follow our conscience.
Larry: Wow. You mean you were using birth control too?
Larry: Vatican II says we are now heart people, not head people.
