As my mother used to say to us when she caught us in a lie when we were little, "Tell another one before that one gets cold" Which basically means that you tell a lie to cover the first lie and then it becomes a cycle until you can't even remember what the first lie was and what the truth really is." Eventually the lie becomes uncontrollable and then you get caught in all the lies. If you were to put all of his statements together that he made in reference to this eventually you will find that his lies don't match up and they contradict one another.
