Undo your drunk hate mail

So Gmail has come out with an Undo Send features, giving all of us a 5-second window to take back mispoken words, now you can click undo while the email is processing or 5-seconds after (it may be updated to ten seconds in the future).

I'm pretty happy about this feature, I tend to write faster than I think. Now, all I need is an undo function for my text messages, and my mouth.
