In one of the most (supposed) unpatriotic acts by an athlete in sports history, Rashard Mendenhall let the world know about his belief in 9/11 conspiracy theories and his interesting take on on the world's most hated terrorist. Feel free to speak your mind, but don't get mad when that endorsement cake stops rolling in. Without a doubt, the most outrageous sports tweet of 2011...so far. We're still following you Arenas and Dockett. #nostalker
