1. Go to a second-hand store and buy a pair of men's used size
14-16 work boots.

2. Place them on your front porch, along with a copy of Guns
and Ammo Magazine.

3. Put a few giant dog dishes next to the boots and magazines.

4. Leave a note on your door that reads:

Hey Bubba, Me, Big Jim, Duke and Slim went for more ammunition.
Back in an hour. Don't mess with the pit bulls - they attacked
the mailman this morning and messed him up real bad. I don't think Killer
took part in it but it was hard to tell from all the blood. Anyway, I locked
all four of 'em in the house.
Better wait outside.

Copied from a local bulletin board, I may have seen it here before also. It's still pretty good!
