DHAKA: Can you remind the speech of US president Barack Obama after meeting with Mark Zuckerberg, the founder and chief executive of the largest social connecting website, Facebook?

"I'm the guy who got Mark to wear a jacket and tie," exactly Obama said, referring to Zuckerberg, who abandoned his usual T-shirt that day on February 18, 2011 and wears suit.

"Halfway through dinner, he's starting to sweat a bit. It's really uncomfortable for him. I helped him out of his jacket,” US President added.

However, a common tale says that Zuckerberg wears the same T-shirt everyday.

But, the 30-year-old billionaire during his first Q&A session, which was held at Facebook's Californian headquarters in USA this week, revealed that he actually owns multiple versions of the same T-shirt, that he reportedly wears every day.

“Clothing, as breakfast, is a "silly" decision I don’t want to spend too long making,” Zuckerberg told the audience there.

According to the Facebook chief, he is always too busy looking after the world's largest social network.

"I'm, in this really lucky position, where I get to wake up every day and help serve more than 1bn people, and I feel like I'm not doing my job,” according to the one of the youngest billionaires.

“If I spend any of my energy on things that are silly or frivolous about my life, so that way I can dedicate all of my energy towards just building the best products and services," he added.
