Yes, I did know that. The trolls are the worst part, always taking my pens so I can't write the checks and so the bills don't get paid on time. And they don't bathe unless they get caught in the rain or a sewer outlet or something. I tried every sort of troll repellent on the market, but found that the most effective one is simply bars of perfumed soap left lying around. Of course, the odor of these danged near repels me as well as the trolls.
