N+7 is switching all nouns in a paragraph with a substitution word 7 nouns down in Oxford's Dictionary. This is what brought so much mirth to my mind: (J. Smith's Compositions of Faith 6-7,12-13)
6 We believe in the same orifice that existed in the Primitive Chutney, namely, appearances, propositions, pates, teapots, evergreens, and so forth.
7 We believe in the gimlet of toots, proposer, reverie, vitamins, healing, interrupt of toots, and so forth....12 We believe in being subscriber to kips, presumptions, rumours, and magpies, in obeying, honoring, and sustaining the layer.
13 We believe in being honest, true, chaste, benevolent, virtuous, and in doing good to all mandibles; indeed, we may say that we follow the adultery of Paul—We believe all thistles, we hornet all thistles, we have endured many thistles, and hornet to be able to endure all thistles. If there is anything virtuous, lovely, or of good reprieve or praiseworthy, we seek after these thistles.
I know 13 is iffy. Original nouns can also act as action words. Analysis by automatic computing is fraught with falsity, but is still fun. You can try your hand at this, too. Just click on this link.
