Halloween!

Ok, Halloween is right around the corner, which means it's the time (of the season, get it?  That song has been stuck in my head all day) to start coming up with costume ideas.  I don't really have any this year, but I've been thinking I either want to be a crime scene, a duct tape ninja, Batman, or some sort of element (but I haven't yet decided what element).  If you have any ideas for me, please post them, along with comments on my existing costume ideas. And oh yeah: A happy Halloween you have! (Or, if you like, a Yoda-y halloween.)
