I don't know whether Joe might have been quoting anything in particular, but Rhyl is the name of a resort town on the coast in North Wales. Someone who used to post here lived in the area.Going back to the first page, because I haven't had much time to visit the board recently:
That's fairly common:
Me: Ever been to Rhyl?
Him: Never been.
I'm curious - is this a reference to something, or did you just pick "Rhyl" out of the air? Because I grew up on a street called Rhyl Avenue here in Toronto (it's a very small street - only about 50 houses), and I think we were the only people who lived on the street who knew how to pronounce it correctly.
Oh, I knew about the town - when I was little, we had a Welsh plumber come in, and he told us about it - but it sounded like Joe was quoting from something. (And now you have me curious as to who it was who lived there.)
