You should write a fic about Simon and Jayne in the SAME SITUATION.

I shall call it 'Dryer Balls: The Mystery', and it shall be a domestic who-dun-it, with sexing in the laundry room. And debates about how to get that laundry soft and fluffy.

(Is it bad that I actually have written a Jayne/Simon fic involving laundry and sex in the laundry room?)
