There are examples of artworks involving instructions which are perhaps only meant to be read or heard, the result of acting upon them left to your own imagination. Perhaps useful to remember: being given an instruction, being told to do something - this of course is real, and it has an effect, regardless of whether or not you carry it out.

I think that it's interesting that this piece can exist in a live way if you simply read out the rules. The projection or threat of the resulting event is already quite palpable, but that a group of people once actually did do this (apparently true - there are photos) somehow grounds it even more - like the weight and inertia of that drunken evening is carried through into the here and now, simply through reading out the instructions / rules of the so-called 'game' - not least of course because the 24-hour news cycle has not stopped since they originally played it.
