These are the $10 Darth Vader and Stormtrooper porch light covers available from ThinkGeek. They make perfect Halloween decorations. Me? I don't have a porch light. I do a nightlight though, because i don't f*** with ghosts. "Awwwww, little GW is afraid of ghosts." Hey -- you have no idea how many people have died in this apartment. Sleep in my bed one night, I dare you. I get to be little spoon though because I don't like having my back exposed to them.
Keep going for a shot of the less-cool looking Stormtrooper one.
Thanks to Luc, who agrees that Darth Vader one could really use a red lightbulb inside for EXTRA EVIL.
