A note to the neighbor that keeps stealing my laundry detergent: Yesterday I put hydrochloric acid in the washing machine and potassium permanganate in the laundry detergent box. The next time you'll attempt to use my "detergent", the compounds will mix to form chlorine gas that will burn your eyes and melt your lungs, killing you slowly and painfully. My lawyers inform me that legally, this constitutes "murder" - I call it "justice".

Rather embarrassing - it seems these days I'm repeatedly washing my clothes on too much heat. It's the only rational explanation for this.
