Mis-Made Bill by Royal Magic

Effect: The magician borrows a dollar bill and shows it on both sides.  The hands are otherwise empty.  The bill is folded in half and then in half again.  A magical gesture and the bill is unfolded, thus transforming it into a "Mis-Made" dollar bill.  The "Mis-Made" bill is refolded and then unfolded changing back to its original form.  The bill is then returned to the spectator.
