Kurt Vonnegut excerpted in Harper's Magazine:
I. With the agreement that my wife will not nag, heckle, or otherwise disturb me on the subject, I promise to scrub the bathroom and kitchen floors once a week, on a day and hour of my own choosing. Not only that, but I will do a good and thorough job, and by that she means that I will get under the bathtub, behind the toilet, under the sink,under the icebox, into the corners; and I will pick up and put in some other location whatever movable objects happen to be on said floors at the time so as to get under them too, and not just around them. Furthermore, while I am undertaking these tasks I will refrain from indulging in such remarks as “Shit,” “Goddamn sonofabitch,” and similar vulgarities, as such language is nerve-wracking to have around the house when nothing more drastic is taking place than the facing of Necessity. If I do not live up to this agreement, my wife is to feel free to nag, heckle, and otherwise disturb me until I am driven to scrub the floors anyway—no matter how busy I am.
