Man, why didn't I think of this. I've seen video of people social engineering their way through many restricted areas in the past; some claiming to have forgotten something in the target locations, others claiming to be Jason Biggs from American Pie fame. None of them are quite as simple, and effective, as just claiming your the DJ! Watch as this man gets into every club he tries just by claiming he's the DJ and is spinning shortly. Watch to the end of the video to see some reasonably funny attempts at DJ social engineering in completely random places.
