Go to the iTunes App Store and search for 'You Promised' and download it for only 99¢
You 1) Name your Promise; 2) Write the Agreement and 3) Record each voice saying "I Promise." How stinkin' cute is that? I can think of a few people this app would come in handy for (and they aren't all kids).
The app is super easy to use and genius, in my opinion.
