One of the more novel apps recently seen in Google Labs is Mail Goggles - an application designed to stop you sending emails that maybe you shouldn't.
If, for example, you set the application up to work on a Friday night - when many people have had a few drinks - it will ask you several maths questions before letting you send the message. The aim of the app is to make sure you're thinking clearly enough to send the email and thus prevent any drunken missives reaching bosses and ex-loves only to be regretted in the sober light of the next day.
