A big thanks to Victor for pointing me in the direction of Kevin Poulton (AKA Sad Old Biker). His Valentine's Day creation plays off of the classic Vader line to humorous effect. It's amazing how emotive those LEGO Stormtroopers can really be.
You can see more of Kevin's great photography on Flickr, and you can purchase prints or cards featuring his work on RedBubble.
So far this is turning out to be quite the Star Wars/Valentine's themed day!
