Facebook founder Mark Zuckerberg claims he can change a diaper in 20 seconds

Facebook founder Mark Zuckerberg has revealed a skill – the social media guru claims he can change a diaper in 20 seconds. After becoming a parent for the first time in November 2015, Zuckerberg says he timed himself to get better.

"I am competitive guy, I time myself to get and better, and I got down to 20 seconds," said 31-year-old Zuckerberg to an audience in Berlin. "The trick is to slide the new diaper under the old one." Zuckerberg was in Berlin to receive an award from German publisher Axel Springer.

Zuckerberg often takes to his official Facebook account to post family pictures of his wife Priscilla Chan and baby daughter Maxima. In December 2015, he posted a picture of him changing his daughter's diaper with a caption that read: "One more down, thousands to go."

One of the users replied to his post saying: "I'm geeky but I actually did calculate the rough number of diapers; I thought thousands might have been hyperbolic, but it's not -- that's the right order of magnitude. Hope it's going well Mark!" To which Zuckerberg replied: "Yeah's it's probably 5000+ diapers all in!"

He has also joked on his casual work attire as he is mostly seen in a t-shirt, jeans and sneakers at work. "I have coloured ones [t-shirts) too but I wear them only the weekend," said Zuckerberg. Zuckerberg named his daughter Chen Mingyu explaining that while Chen was her mother's family name, Mingyu represents "our hope for a brighter tomorrow for the world". The Facebook founder had studied Mandarin prior to his first visit to China with his then-girlfriend Priscilla. He reportedly went on a two-month paternity leave at the birth of his daughter.
