OK, works now. :-) Was honestly surprised that almost everything was additive, i.e. I could just throw in another word or punctuation mark. (On a second run I got "can't contain an N" and I had to change "king" to "rook" and then I had to change the initial "G" to "K", but pretty small.) I was prepared to need to use "saturn" so that it could also satisfy the day-of-week rule, because a length limit would pop up.
Still, brief but entertaining. :-)
