I like to take a pocket full when ever I go out. Just start leaving shells in inapropriate places. Public bathrooms, resteraunt booths, pay phones, any where in the grocery store (produce, frozen foods etc.), stacked neatly at the gas pump, If you leave a pile in between parking spaces its the first thing people see when they step out of the car. Sure its juvinile, but I live in the sticks and we'll take any entertainment we can get.
