The Scarecrow motion-detecting sprinkler system
Perhaps killing two birds with one stone isn't the best euphemism for the Scarecrow motion-activated sprinkler, since it will probably most appeal to animal lovers who abhor the whole electric yard-fence thing. Well, those guys and your particularly harmless antisocial neighbors who just don't realize that a little water just isn't going to keep those pesky kids from leaving flaming bags of dung on your doorstep. But at least this may put the bag out for you.
