How to avoid drunk emailing, or not?

This is hysterical. A couple of weeks ago, I heard about Mail Goggles--something Google came up with to keep people from totally embarassing themselves. It activates between 10pm and 4am on weekends, and is designed to keep people from drunk emailing by making them answer 5 math questions before the mail is sent. Sort of genius, but I definitely have doubts about it. This girl's "test" for Time magazine is pretty hilarious--i'd love to try it too, but it could be dangerous!
