In the video Zuckerberg posted to Facebook Thursday, filmed by his dad, the Facebook CEO lets out a single "yay" as he reads the email saying he would join Harvard University's class of 2006. His father's reaction is noticeably more excited. "Alright! Yes! Great!" his father yells off-camera.
The Facebook founder, who ended up dropping out of Harvard, posted the video in light of his upcoming commencement speech at the school on May 25.
"My dad took this video when I got accepted to Harvard," the caption read. "Next week I'm going back for commencement to get my degree. #tbt"
In a comment, Zuckerberg added, "Before I went to college, my mom bet me I'd drop out and my younger sister bet me she'd finish college before me. I bet them I'd get a degree. Now I suppose the cycle is complete."
