What Would You Steal From Nick Jonas’s Dressing Room?

It's June 27th at Boise Music Festival.  Somehow you've wandered backstage and are walking through the rows of trailers.  You notice security isn't paying attention to the door that's cracked open.  You get curious.  Quietly creep up the stairs and look inside!  It's Nick Jonas's dressing room! OMG!  If you knew you wouldn't get caught, what item do you steal?
