Claire found this a while back and I've been meaning to post this for a while, but just haven't had the chance.
So, back to the the question - When is a fish not a fish?
When it's spelt ghoti
Huh?? I hear you say, well let me explain... gh as in "tough", o as in "women", and ti as in "nation". Simple really :-/ , but I think I'll stick with spelling it "fish"
