The "vain" part I can tell you. It was last Sunday's gospel reading about the guy who prays "O God, I tithe and I fast once a week, thank you for not making me like the rabble or like that scummy tax collector over there" versus the tax collector who prays "Oh God have mercy on me, an unworthy sinner"

Agreed, that is a good example of a vain prayer, but I doubt he used it repetiously, but if we knew he did the Hail Mary, we would have a good example wouldn't we?
Lol, we would also know we were in a time warp.(^g^)
