Halloween Costume Idea!!!

Halloween / my sister's birthday is almost here. I really haven't had any costume ideas until now. My friend, Angelo had a crazy idea on what I should dress up for on Halloween. All I have to say to that idea is that I do need "change". I even think I need to make some "progress" on choosing this costume, because "yes we can" choose the right costume together. I say we, because I want you,"America" to help give me more ideas for a costume. Please comment me with more ideas
