Affirm A Daily Prayer That Slap Upside The Head

So many preachers in the 70's and 80's were spotted on the tube giving someone a good slap upside the head then shouting, "Healed!" Really? I'm not sure I've come across the Bible verse that showcases the most famous son of using such a technique. I do wonder if preachers didn't have a way of shaping several generations in the way of creating a false front of hope, faith and recovery. One big hit on the head followed by, "Healed!" Does God ever roll his or her eyes when witnessing man's walk toward helping others resume?
