20 Ways To Confuse Trick-Or-Treaters:

1. Give away something other than candy.  (Toothpicks, golf
   balls, bags of sand, etc.)

2. Wait behind the door until some people come.  When they get
   near the door, jump out, wearing a costume, and holding a bag, and
   yell, "Trick or Treat!"  Look at them, scratch your head, and act
   confused.

3. Fill a briefcase with marbles and crackers.  Write on it, "Top
   Secret" in big letters.  When trick-or-treaters come, look around
   suspiciously, say, "It's about time you got here," give them the 
   briefcase, and quickly shut the door.

4. Get about 30 people to wait in your living room.  When 
   trick-or-treaters come to the door, say, "Come in."  When they do, 
   have everyone yell, "Surprise!!!"  Act like it's a surprise party.

5. Get everyone who comes to the door to come in and see if they can
   figure out what's wrong with your dishwasher.  Insist that it makes
   an unnatural  "whirring" sound.

6. After you give them candy, hand the trick-or-treaters a bill.

7. Open the door dressed as a giant fish. Immediately collapse, and
   don't move or say anything until the trick-or-treaters go away.

8. When you answer the door, hold up one candybar, throw it
   out into the street, and yell, "Crawl for it!" 

9. When you answer the door, look at the trick-or-treaters,
   act shocked and scared, and start screaming your head off.  
   Slam the door and runaround the house, screaming until they 
   go away.

10. Insist that the trick-or-treaters each do ten push-ups
    before you give them any candy. 

11. Hand out menus to the trick-or-treaters and let them order
    their candy.  Keep asking if anyone wants to see the wine list.

12. Get a catapult.  Sit on your porch and catapult pumpkins
    at anyone who comes within 50 yards of your house.

13. When people come to the door, jump out a nearby window,
    crashing through the glass, and run as far away from your 
    house as you can.

14. Answer the door dressed as a pilgrim.  Stare at the
    trick-or-treaters for a moment, pretend to be confused, and 
    start flipping through a calendar.
 
15. Instead of candy, give away colored eggs.  If anyone
    protests, explain that the eggs are the only thing you had 
    left over from Easter.

16. Answer the door dressed as a dentist.  Angrily give the
    trick-or-treaters  a two-hour lecture on tooth decay.

17. Answer the door with a mouthful of M & M's and several
    half-eaten candy bars in your hands.  Act surprised, and close 
    the door. Open it again  in a few seconds, and insist that you 
    don't have any candy.

18. Hand out cigarettes and bottles of asprin.

19. Put a crown on a pumpkin and put the pumpkin on a throne on your
    porch. Insist that all of the trick-or-treaters bow before the
    pumpkin.

20. Dress up like a bunny rabbit.  Yell and curse from the moment you
    open the door, and angrily throw the candy at the 
    trick-or-treaters.
    Slam the door when you're finished.
