I have even better idea - why don't you all practise your psychic skills and make a psycast where you predict what is going to be in it. Of course we could all get drunk and have a plastercast.
Since you 'get plastered' is it something we do to each other, or does the plaster-fairy deliver it to us in the night? The Cologne modern Art Gallary had a wonderful piece which was plaster casts of 'the artist' in the act of casting moulds of his nude model. the artist/model are of course painted realistically, so its plaster faking the act of plaster faking. they also had the plaster cast fake of the flag-on-iwo-jima but the soldiers are raising the canopy over an italian coffee shop table.. (this was back in '82, no idea if they are still there)
