I had a brief look at that page, though something on it keeps crashing my browser, and I agree entirely about its Screwtapish origins. I can just imagine his amusement about inventing a way to screw up humans which is even more fun than the passive aggressive 'generosity game' (Person one proposes an innocuous activity, such as tea in the garden. Person two dislikes the idea, but 'generously' agrees in a sulky tone of voice. Person one, in similar tones, says 'oh all right, we'll stay indoors then'. Repeat, ad nauseam, and with a bit of luck no-one gets any tea at all)
