My advice to Obama, is to keep the hell away from Bernie Mac.This Guy was the singer of the seventh inning stretch at the Cubs game when Bartman turned the game on it's heels. But really, maybe it was Mac who, after the stretch song, when normally everyone who sings it, shouts, "let's get some runs," strayed from the script and virtually put the game in the refrigerator, calling it done and the cubs golden. He's a jinx.
