I saw this this morning on my way in to my real job - I work with lasers (ohh ahh!(it's not that cool)) - and it made me LOL so good:
It reminds me of that episode of The Big Bang Theory when Sheldon explains what AFK means (away from keyboard) while he's playing a video game and Penny says "Oh, I see" and Sheldon asks what that means and she says "Oh. I. see." and he still doesn't get it. Yep, that.
