From the mind of Daniel Garcia comes a torn and restored card routine that will make you smile.
You demonstrate: Your "CRIMP" is actually a hilariously large chunk that you tear off of the corner of their signed card.
You explain: This "CRIMP" allows you to cut to their selection "just by feeling for the missing part".
You confess: There's one small problem with your method... sometimes a spectator with "a highly trained eye" will notice the extra piece. With this, you pick up the torn chunk of card from the table and place it on top of the spectator's signed card.
Immediately hand your spectator their signed card. It's COMPLETELY RESTORED.
