Christina Aguilera and Jimmy Fallon perform 'Your Body' with office supplies

Christina Aguilera sat in with Jimmy Fallon and his "Late Night" house band, The Roots, for a unique performance of her new single, "Your Body" from the forthcoming album, "Lotus." 

The instruments included Jimmy's iPhone and various items found around the office, from coffee pots to printer paper.

Fallon even joins in on the vocals. What do you think of this performance? Ingenious or worthless?
