Okay, my pick for most original Halloween costume of 2010 goes to these homemade Angry Bird Halloween costumes. Visit their website, to see more fantastic costume pictures. If you don’t know what Angry Birds is, then you must be on another planet. It is one of the most popular game downloads on iTunes (and now Android). The guys who made these costumes are now selling them so you can parade around as one of these adorable birds with attitude!
