They say that imitation is the sincerest form of flattery but I don't know how sincere Jimmy Fallon was or how flattered Taylor Swift was by Jimmy's impersonation of her in a mock audition for "The Voice". The idea behind the skit was that Taylor should have been the star of the Super Bowl halftime show rather than Madonna. As for Jimmy's singing, well, I doubt he'll be giving up his night job.
