海军罪案调查处 海军罪案调查处 Picture Hunt!
I stole this idea from girly_girl on Booth and Brennan spot. All the credit goes to her!
Anyway, what you do, is someone asks for a picture and then the next person puts the picture on their reply with a request for another picture.
IE. A picture of the team in the evidence locker in 'Internal Affairs'!
