He leaves all his washing inside out or screwed up in a ball. Dh and me get fed up of turning it back to hang out the washing and put it away. I've asked him to stop several times and if he's still up hand it back to him. He still does it.
Dh thinks we should give it back to him inside out so that he HAS to put it back, or better still just turn all his clothes inside out.
I'm thinking it's a great plan.
