Facebook security

So when you go to post a link on your wall or someone else's wall, facebook requires you to be able to read and re-type a couple of words for security purposes. I think it's a test to see if you are drunk or high, cause even when sober, the words look like they are written in Arabic. Here's the one I got, for example. I think we should have this for all interactions, not just on facebook. This would stop any drunk dialing, drunk texting, drunk going up to and ex in the bar and making a scene. Think about it. If we had to pass this test before we acted, well, the morning after would not be as painful.
