Your friends probably tell stories about you to their friends of how awesome you are at magic (if they are not, they should be) and when you meet these people they will most likely ask you to do a trick. And ofcourse you are not prepared. (maybe you are though) So what trick do you do, when you are confronted without props or set-up? For me, I either say 'No, piss off.' or do the twisting arm illusion thing that David Stone does. J.
