The University of Southern California invited Will Ferrell to speak at the class of 2017 graduation ceremony on Friday ? and it went exactly how you'd imagine Will Ferrell giving a collegiate commencement speech would go. The comedian, who is a USC alum, received an honorary doctorate before launching into the main speech of the ceremony. He ended his speech by singing "I Will Always Love You" sensually, and it was, wow, a real tear-in-my-eye moment.
