Sunday, May 17, in Washington, DC, Apple CEO Tim Cook delivered the commencement address to The George Washington University’s class of 2015. Cook cracked jokes about recycling any non-iPhone devices those in the crowd may have had, and also took a photo of the graduates with his own iPhone at the end of his speech.

Cook spoke about Steve Jobs’s influence on his career. Jobs, said Cook, made him question everything, including the role of work in his life, and what kind of satisfaction he should be deriving from it.

Cook also talked about meeting other famous figures, including Jimmy Carter, who he admired, and George Wallace, the racist governor of Cook’s home state of Alabama. Shaking Wallace’s hand, said Cook, felt like a “betrayal.”
