lol I know. I read far too much Terry Pratchett not to
It took me several years to realize that marzipan is a candy substance that is water soluble because I only ever heard it mentioned by British authors, one of which is Terry Pratchett where he mentions that someone has the survivability of a marzipan duck. (which assuming what I've just said, probably isn't very long)
Anyway I've not heard very many people use daft other than British writers (and Pratchett fans) either.
You could say I was checking to see if you were one or the other.
