Facebook founder and CEO secured admission into Harvard university in 2006 but dropped out eventually to build your darling social network, Facebook.

Zuckerberg’s father filmed his son's reaction to getting into the prestigious university and Mark shared it yesterday in nostalgia while disclosing that he plans to return to the school to complete his degree.

“My dad took this video when I got accepted to Harvard. Next week I'm going back for commencement to get my degree,” Mark said in a Facebook post.

In the video, Zuckerberg’s father, Edward records the young Mark as he opens the long-awaited email.

Mark lets out a very calm "yay" when he discovers he's been accepted. By contrast, Edward freaks out – obvious elated by his son’s achievement.  

Edward is radiating with pride at his son's accomplishment. The dog, on the other hand, isn't as impressed.
