Frank Caliendo is one of the best impressionists of all-time. If you are an NFL fan, you know him for his impressions of John Madden and Terry Bradshaw. He is also known for his impressions of Robin Williams, Robert De Niro, and William Shatner.

In this video he is on the "Mike & Mike" radio show, narrating LeBron James' letter to Cleveland as the voice of Morgan Freeman. It is incredible, and hilarious.
