I've just done a search as well and can't find anything to with football, tenis, rugby or cricket !
It's true I was hitting the qiri hard on my last read through, but I can't belive I got it that wrong. It was sports related. It was related to a "as big as" or "the size of a".
Memory is a strange. Now I'm destined to spend the rest of my days scouring the accursed halls of Cil-Aujas in search of The 20th Century Sports Reference.
Fair enough damnation for opening a thread on such a flimsy premise ?
Are you sure you couldn't have read that reference in another book (maybe even another fantasy book) you were reading at around the same time? It's easy to be mistaken about what book/series it did come from, similar things have happened to me before (and to many others, I'd suppose).

Speaking of words/phrases that stick out, I'll admit by being thrown out of the text by the word "okay" a few times. Now, it's not like I know anything about the history of that word (and English isn't even my first language anyway) so I could be mistaken, but I always thought it was a fairly modern thing.
