Many years ago a friend, who shall remain anonymous, used to live across from said orphanage and when exacerbated by her rowdy kids, used to say, "I'll send you lot to the orphanage if you don't behave!"
An empty threat until one day, a long lost friend turned up on her door and as she introduced the friend to the kids she added casually, "She's from the orphanage."
To which the kids howled, flew into their bedrooms and did not misbehave again - ever.
