My scenario is that I am locked in a room. During a half hour period, I will be 'visited' between 3 and 6 times. Each visit, the person decides what instrument they wish to use, in whatever position they choose and to give me between 3 and 6 strokes. That could be up to 6 different people and between 9 and 36 strokes. Not knowing is the key to this. One stipulation though, one 'visit' must be OTK and slipper,(cos I like it).
