Mail Goggles

Mail Goggles is a Google Labs feature for Gmail that makes you solve math problems before sending an email late at night on a weekend. It's set up so you don't drunkenly email people you probably shouldn't be talking to anyway. More often than not, I end up sending real emails on purpose on weekends, so Mail Goggles doesn'r help much.

Plus, it turns out that I can still do math when I'm pretty drunk.

(No, there's embarrassing story to go along with the above statement.)
