One of the funniest things I ever saw concerning Halloween was an old Dave Berg thing in MAD Magazine.
Kids come to the door with paper sacks.
Friendly neighbor drops a scoop of Ice cream in each sack.
The kids are happy they got ice cream.
Last frame: The friendly neighbor raking up the candy that dropped out of the bottom of the kids paper sacks when the ice cream melted.
That gives me an idea...
