I rely upon a thing called a "swatter." But then I don't have dogs.

There was a health worker visiting some of the farms in the backcountry here, trying to convince the hidebound old ranchers that some of the "modern" advances were good ideas. One in particular was adamant about window screens -- ABSOLUTELY NOT! Too expensive and besides, his daddy didn't need 'em and his granddaddy didn't and you know the sort of person. Told her all he needed was to sprinkle a little lime in the outhouse now and then and the fly problem was solved.

Couple months later the health worker dropped by and found the house replete with screens: window screens, screen doors, even screens over the vents in the eaves and in the attic. She was stunned, and asked the old boy what had converted him him. He hemmed and hawed around and find said, "Well, there wuz these white footprints on ma food."
