This one is sweet, quick to learn, and provides you the opportunity to really mess with the poor sap
who is the target of your performance. There is really no reset needed, and you can certainly do it
a couple of times before moving on to something else.
I performed it for one friend who was
increasingly convinced that I really was reading his mind. Freaked him out a little, actually...
Anyway, this is a fun one that fits nicely in your jacket pocket!
