You will lie down on a bed in the spreadeagle position.
I will pluck four long hairs and tie each of them around your wrists and ankles. I will tie four ribbons to the four corners of the bed and around the four hairs.
I will then use all the skills and tools of pleasure and pain at my disposal to make you either break one of those four hairs or make you speak. If at the end of an hour you have not said a word and all four hairs are intact: you win. If you snap any of the hairs, or you say anything at all in that hour: I win.
You game?
