How To Sneak Into the Super Bowl With Social Engineering
danielkennedy74 links to an instructive story captured on video introduced with these words: "Sneaking in near press/employee access points without going thru them, zigzagging through corridors, and once carrying a box so someone opens a door for them, two jokers from Savannah State University social engineer their way into Super Bowl XLVII for the most part simply by looking like they belong."
USA Today has a slightly longer article.
Maybe they can use their social engineering to get out of Gitmo after this video gets labeled by people with no sense of humor as terrorist training material.
Actually, carrying a box that looks burdensome implies you are doing work, so people assume you belong there. I once walked into the courtyard of a large "fruit company" by helping a vendor carry in a box. He assumed I worked there, and they assumed I was with him. I even got a name tag at the door.
