Mark Zuckerberg may be the most famous Harvard dropout ever, but back when he got his acceptance letter, he was ecstatic, as anyone would be if they got in Harvard. 

Mark posted a throwback video from 2002, obviously on Facebook, sharing with everyone the exact moment he found out he got in. He was part of the class of 2006, but famously dropped out in 2004 to focus on Facebook.

But, he will still be getting his honorary degree at the university's upcoming graduation ceremony on May 25, where he will be giving a commencement speech as well. 

"My dad took this video when I got accepted to Harvard. Next week I'm going back for commencement to get my degree," the 33-year-old billionaire wrote in the caption accompanying the video.

Also, in the video, he is still rocking his signature grey t-shirt. 

Hearing that Mark got accepted, his father, Edward Zuckerberg, asks, "Are you serious?" 

"Alright! Yes! Great,” he says as he high-fives his son. His father goes on to introduce his son as one of the newest members of Harvard’s class of 2006. 

"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," Mr Zuckerberg wrote in the comments section on Facebook.
