Anyone for nun wrestling?

Explaining to Tilly and Reuben about how one of my patients is looked after by a Nun. 
Reuben "What's a Nun?"
Me "a bit like a lady priest, they live in a Nunnery"

Reuben "Do they do Nun wrestling?"
"I don't think so"

Reuben "What is Nun wrestling?"
"I don't think I've heard of Nun wrestling"

Reuben "I think they do Nun wrestling."

I've got no idea where that came from! Luckily mum not in the room.

Update: Nun wrestling - the vicar's magazine in Wallace and Gromit Curse of the Wererabbit. How'd he pick up that detail?

Still we're a broad-minded bunch at 440A.  Recently there was a discussion that went something like this:

Reuben (slightly aghast) "Did you know, there are some people who don't believe in Christmas!  They're called Motleys"

Hannah (slightly bemused, wonders if he means Muslims but takes this at face value) "Well, some people think the Jesus stories are true and so they celebrate Christmas, some people don't think the Jesus stories are true but they still think it's fun to celebrate Christmas anyway, and in some parts of the world people believe in different gods and they have their own festivals instead of Christmas"

Cue 5 minutes discussion of major world religions, which concluded like this:

Reuben "So those people don't have god?"

Hannah "Well, they don't have the same god as Christians or Jewish people"

Tilly "But they do have noodles" 

Reuben "Tilleeee! They don't have noodles"

Tilly "Yes they do have noodles"

Hannah - actually, Hannah can't say anything at this point as she is having to concentrate too hard on keeping the car on the road.

Has our daughter been evangelised by members of the Church of the Flying Spaghetti Monster, we wonder, or merely blessed by His Noodly Appendage?  (If you haven't a clue what I'm on about, there is background here and the original open letter to the Kansas School Board from Bobby Henderson here.
