Once upon a time, there was a man trying to write a story without using the character than comes before "m" and is just after "k", you know. I'd write it down but I'm not permitted. (So far so good). He found it a strenuous activity but pushed forward anyway. It occured to him by the fifth sentance that it might be easier than he thought. He just had to write anything and if he discovered that forbidden character appeared he just had to go pack and change the word for something not so forbidden, if you get my drift.
