If someone ever comes up to you and claims they are psychic, simply ask them when the last time they won the PowerBall jackpot or the Mega Millions jackpot. If they tell you they don't play the lottery, tell them they are just as full of shit about that as they are about their "predictions" (be sure to use the air quotes) and then walk away.
