It's good to know the geniuses over at Google Labs can get just as stupid as I can after a night out. The company recently unveiled "Mail Goggles," a feature that requires users to correctly finish five math problems in a minute before sending late-night e-mails.

Basically, it's a breathalyzer for your computer. But how well does it work? I tried it out to let you know.

Setup is easy: Go to "Settings," then "Labs," then choose the times and days that the goggles should be activated and the level of difficulty of the quiz.

I started my test run with two-for-one margaritas and a friend I like to call Jose, then set to work trying to e-mail old "friends." My biggest problem with the app is that it gave me unlimited tries to get the questions right -- when I answered incorrectly, I got a message advising, "Water and bed for you. Or try again." Try again? I think a zero-tolerance policy would be more effective -- say, "Turn off Britney's 'In the Zone' and lie down immediately" followed by an automatic shutdown.

Even on the hardest level, the equations never went beyond simple arithmetic that could be quickly worked out on the computer's calculator -- some "My Dear Aunt Sally" stuff might make this a little more tricky

I wish they'd develop a similar application for phones, since drunk dialing and texting is definitely a bigger societal problem than drunk e-mailing. If Google Phone could lose my exes' numbers after cocktail number four, it might finally get the edge it needs to knock the iPhone out of the ring.
