Deej and I play a word game from the newspaper every day. We like to live close to the edge.
You know the kind of thing: a circle of 9 letters, and you have to find the 9 letter anagram and as many words with 3+ letters as you can.
Obviously we don't check the answers in the paper. The point is to BEAT EACH OTHER. As it is so important to win, we each instituted a separate list of 'dodgies' for back up. In my case this often consists of interesting-sounding words that, if they don't exist, jolly well should.
Anyway, we were comparing words and when he said he had 'radii' I said disparagingly, "Oh, what's that meant to be then, the plural of radio??"
Oh shut up.
