My own phantom priest is a better one. He hangs around all the time, so I've never had an auto accident. Which beats the crap out of having one that lets you get all squished up and then shows up, all heroic and shit.
Of course I've never actually seen mine. Nor even suspected he existed. But he's still doing a great job.
Where he was when I was carefully picking out my various ex's, I dunno. He probably didn't know much about women.
