It's hard to believe that it's been ten years since 9/11 -- and harder still to believe that Pauly D is shown talking about something other than fist pumping and GTLing, not to mention one of the biggest tragic events in recent American history. No matter: Lady Gaga, Julianne Hough and a slew of notable names are there as well to converse about how to effect change and remember the day in this video promotion for the 9/11 Tribute Movement, which encourages people to participate by describing "what you will do this year, a good deed, charitable activity, or other plans, to honor the 9/11 victims, survivors and those that rose in service in response to the attacks."
