The master of impressions, Frank Caliendo, has done his fair share of Jon Gruden (and Jay Gruden) impressions the past few years, but he's never done it quite like this.
Here, Caliendo takes on the Gruden persona with his subject, the star of "QB Camp" and the head of the Fired Football Coaches Association, sitting right across from him on his own home turf.
Impersonating the master in his own environment is a tall order, and Caliendo nails it like a pro.
