How other people deal with door-to-door idiots...

I read the best of Craigslist occasionally. Funny stuff, sometimes. I came across particularly funny post tonight that I identify with:

best of craigslist : Door to door religious idiots:

"Still out of breath from the fight, sweating, covered in scratches and blood and hair, and carrying a nail trimming tool in one hand, I fling open the door. The picture-perfect charismatic family has decided to let the little girl be the front man. She looks to be about eight years old. She's standing on the front porch, while Mom, Dad, and Little Brother - about five - are standing a few feet back on the walkway. I grit my teeth in my best Dirty Harry impression, look directly at the little girl, and say, 'Yes?' "

I wrote about my own manner of dealing with random people ringing my bell a few months ago. Perhaps I should get some fake blood.
