After one performance, I was asked why I had to do it inside a folded card. I had the feeling others
were thinking that. It's easy enough to "make", although some precision is required there, as well
as in the performance. Bonuses are that it's a borrowed bill, although the borrowed one has to be
similar to the gaff bill, and that's not always a given. I never had that "Wow! I can hardly wait
to do it to the next person," feeling. For me, it's a "C+".
