Flash Mob

I'm 100 % down to initiate a flash mob next week on Thursday. I honestly feel like it'll be a challenging event but one of those that once it's done you're so glad you participated in it. In clash we saw a few videos to stimulate ideas and I got to say that my favorite was the X-Box commercial where they start a finger gun fight inside what looks to be a mall. My only thing is that it is advertising violence and I know that one student in the class felt strongly against promoting violence within our flash mob. Truthfully I have no idea what to do, I know I want the class to do something original but its pretty hard to come up with original ideas.
