How To Get The Truth Out Of Somebody

Doesn't it just drive you up the wall when somebody blatantly lies to you. Looking you in the eye and refusing to tell you the truth. If you really need to get the truth out of them, you play it cool, act like there is nothing wrong. Then convince them to lay on the floor, on there back. Once there laying down you sit on there hips ands take consecutive 3 inch punches after every punch you say "Are you ready to tell me the truth" if they say no, continue. They will eventually get tired and admit the truth.
