A while back there was a "true" story (urban legend) about a guy
who was interrupted by the doorbell.
Upon opening the door he found some religious nuts who were very
annoying. As he was in the middle of preparing dinner, he'd gone
to the door with a very large knife in his hand.
At some point, he called out to his friends asking if they'd gotten
virgin ready for the sacrifice. At this point, the callers fled
from the home, never to return again.
