Have you ever taken a do over? As a kid, did you ever swing at a ball and miss, and then say "do over, do over?"

When we get older we still do them, we just don't call them do overs. When we play golf we call them a Mulligan. I was reading how this came to be a part of golf. Of course it isn't part of the official rules, it is what I call "preacher's rules."
