Here's an idea you can use for Halloween. Instead of giving out prewrapped candy, why not hand out some delicious sugar cookies adorned with the Filmation's Ghostbusters logo? That way, you can give kids a tasty treat AND spread awareness of FGB at the same time!
Pillsbury sugar cookie mix, in a tube
Yellow cake icing
Black cake icing
White cake icing
Bake the cookies and cut them into circles. For the logo, you can either use the '75 Classic logo or the '86 Animated logos (worried and/or smiling ghost faces). If you're planning to make this in significantly large quantities for Halloween, you may need to run it by a community center or something to get an assembly line started up--these things are pretty involved.
