This feels like the setup for a Rowan Atkinson bit (though in that he's a minister who says: "The other day, I had a young woman who had just accepted her boyfriend's proposal come up to me and say: 'Father, I need to know - what is the church's stance of fellatio?' and I told her "I would love to tell you what the Church's stance on fellatio is, but honestly, I haven't the foggiest idea what fellatio is,' so she showed me. And ever since then, when someone asks me what the church's stance on fellatio is, I say "I would love to tell you what the Church's stance on fellatio is, but honestly, I haven't the foggiest idea what fellatio is...'")
