The Anti-Time Wasting/Motivational App

Most apps are time wasters but not this one.  It would have a field where you would enter the amount of time you had just wasted watching TV or playing Angry Birds and it would give you an example of someone famous that had done something in that amount of time.  For example if you typed in 90 min it would say "In the time you wasted H. Ford's assembly line could produce a Model-T start to finish."  Or if you typed in 30 min it would say "If you had gone for a walk you would have burned 180 calories."
