For real fun: Keep the lights off, take a set of lensless glasses, hot glue some red LED's on them, run wires from the LED's to a 9 volt, wear a deep hooded cloak, and then run up behind the kids as they walk up on your porch.
Or dress as a Tusken Raider from Star Wars, leap out while yelling "Urk, urgurk, urk! Urk! Urk!" and pick up the candy they drop ince they run from your gaderfi stick.
Who says the kids can have all the candy?
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.
Jump from a tree after the kiddees have their loot.
They drop it and run. You get all the goods.
Ahhhrrg! Matey, a great time for all!
