I believe I have heard of a man (from my catechism when I was younger) who had contempt for Mary, the mother of God. This was during the biblical times, while she was being carried to her tomb on a stretcher of some sort. So the man attempted to use his hands to flip her over on the stretcher, but before his hands made it within a foot, they were sliced clean off for no reason. After he realized what he had done, he reptented, made a perfect contrition, and his hands were miraculously restored.
I don't remember his name, it was a long time ago.
