Hackers took over Harvard's newspaper website and relentlessly mocked Mark Zuckerberg, who delivered an emotional commencement speech on Thursday, 13 years after he dropped out to continue working on Facebook.

The hackers plastered the Harvard Crimson with headlines like 'Mark Zoinkerburg at it again' and 'Breaking: Mork Zinkeltink zonks all over the Internet'.

Pranksters identifying themselves as the 'Winklevink twins' - an apparent play on the Winklevoss twins who famously sued Zuckerberg for stealing their idea for Facebook - later called Gizmodo and denied responsibility, suggesting instead it was the Harvard Lampoon.

Hackers photoshopped Zuckerberg's face so he appeared on the website with no eyebrows and barely any teeth, while headlines read: 'Oops: Mink Pinklebink accidentally 'likes' own commencement speech.'

Other headlines stated: 'Uh Oh: Facebook a Big Grand Hoax Say Fast Kayaking Winklecrux Twins' and 'Breaking: Dum dum computer boy drops out of hard school, learns to kayak.'

Readers soon shared screen grabs of the site on Twitter, while the paper issued a statement saying: 'A few hours ago, an unauthorized user altered The Crimson's website. We regret any inconvenience to our readers.'

But writer Jane Coaston tweeted: 'The Harvard Crimson should not deny they did this because this is the funniest thing I’ve seen all day.'

The website later reverted back to normal, and two individuals claiming to be the 'Winklevink twins' called Gizmodo asserting 'Zickleberg' stole their idea to hack the website.

They denied responsibility and cast the blame on Zickleberg or members of The Harvard Lampoon, who they called 'geniuses'.

The Lampoon, a humorous magazine with a longstanding rivalry with the Crimson, is known for pulling off pranks on the paper.

Zuckerberg returned to Harvard on Thursday to receive an honorary degree 13 years after he famously dropped out of the Ivy League school to focus on Facebook.

The billionaire CEO also delivered the commencement speech, during which he teared up talking about his interactions with an undocumented student who dreamed of attending college one day.
