Truth?

I had to take a peak at this new show: "The moment of Truth." I really didn't find it all that bad, but they did not get up to the most difficult questions yet. The real problem I have with this is it can be entirely misleading. For instance they asked this guy "Have you ever hid something from your wife." Of course the lie detector is going to say your lying if you say no, but how do you answer this. What if the poor guy hid a present he bought for her, or what if he bought a candy bar and didn't tell her. Another question was "do you keep a secret bank account from your wife?" What if he does but it only has $2.00 in it and he keeps it on the side because he is saving to buy her a nice vacation for retirement?" Does this really count as bold faced lying? I guess all this can be explained after the show, but I really think this game might not be all that truthful.
