And this final note. If you've ever wished for some sort of lie detector for the campaign trail? Enter the Super PAC app. It's the brainchild of former students from MIT's media lab. You download it, turn on the TV, find a political ad and the app tells you who paid for that ad and where to find out whether what the ad says is true.

Let's just hope they don't make one that can tell whether you're lying about your weight.
