Artist Steve Casino was eating peanuts one day, when he noticed one was sorta shaped like him. He drew a cartoon of himself with a pen, showed it to his friend who got a big laugh. Steve did a celebrity next, of Joey Ramone and has been hooked since! He basically does nut jobs of people whom he admires.
He leaves the back of the nuts untouched. Why? He loves the happy reaction of people when he shows them the back of a normal looking peanut and then slowly reveals the person painted on the front.
