Safeguard for Drunk E-mailing

While in college, I had the habit of always checking my computer before going to bed and when waking up in the morning. Actually, pretty much anytime I came in and out of the room. Anyway, some morning I would come back to an e-mail from a friend (who I know reads this and I hope doesn't mind!) from sometime in the early e-mail. It would be a drunken e-mail explaining all the craziness from the night before, usually with a boy involved. I loved getting the e-mails, though didn't always think I did a good job of consoling.

The problem was that I wasn't the only one receiving drunken e-mails. Members of the male persuasion also received digital messages, and many that were regretted the next morning. I was highly amused when she sent me a link to Google Lab's "Mail Goggles". With "Mail Goggles" turned on, you have to answer five math questions within 60 seconds before you can send outgoing mail. The difficulty of the questions and the dates/times that the check should be automatically turned on are configurable. Then again, this friend is known to have powers that she can do drunk that she cannot do sober. Since she's already an engineer and great a math, I doubt it'd hinder her ability to do her problems.
