a while back I read where a kid won first prize at his science fair because he rigged a doormat to ring the doorbell when the cat stepped on the mat. same idea!
they go door to door during the day to catch wives at home. when the wives are converted, they turn into Stepford wives which thrill the husbands to no end (because the husbands then become the absolute master of the household.) then they, too, convert. win-win, except for her.
I would guess over 300 hearts would say it all . . .
