Entertaining Father Stone - S1-E2
Father Dougal: Did you ever see that film, Ted, where your man has his head transplanted onto a fly, and the fly's head was transplanted onto the man?
Father Ted: Oh, yes... What was it called...?
Father Dougal: "Out Of Africa", I think. Anyway, your man has the head of the fly and he's chasing his wife all over the place and she's hiding the jam and everything so he won't get stuck in it...
Father Ted: I'll have to stop you there, Dougal.
Father Dougal: Yes, Ted?
Father Ted: No reason. I just have to stop you.
Father Jack: NUNS! NUNS! REVERSE! REVERSE!
Chosen answer: It's characteristic of someone putting on a fake Irish accent.
