A group of future number-crunchers had their commencement crashed by DJ Khaled.
The hip-hop star and social media celebrity gave a surprise performance at the ceremony for statistics graduates at the University of California, Berkeley.
In a video posted by the school, speaker Steve Stout had just finished his address Thursday when he said there was a gift for students.
DJ Khaled then walked out among the grads wearing a baby-blue tracksuit and rapping his signature hit "All I Do Is Win."
The students looked stunned and confused, and few raised their hands in the air as he asked.
The 41-year-old rapper then gave a pep talk, saying the world once refused to believe in him, and now he's onstage with "kids and queens and a generation of geniuses."
"I didn't come out here to do a concert, I came here to praise you young kids for graduating today. This is amazing" Khaled said, noting he didn't graduate college himself so "this is the closest thing to graduation for me."
