U.S. leader Barack Obama's Tv interview skit with The Hangover star Zach Galifianakis became a huge Internet hit on Tuesday (11Mar14), and provided a big boost to the President's new healthcare initiative.

Funnyman Galifianakis was stunned when Obama's aides reached out to FunnyOrDie.com bosses, who air the bearded star's irreverent web series Between Two Ferns, and asked if the zany comic would be interested in sitting down with Obama.

Director/comedian Scott Aukerman explains, "The White House came to us and really wanted to do it. They really wanted to get the word out about the Affordable Care Act and they were looking for interesting ways to do it."

During the spoof chat Obama was grilled on topics such as North Korea, his birth certificate and being "a nerd".

The video quickly took off on the Internet. It premiered at 7am in New York and in just two hours, the online interview had been viewed by three million people - and the FunnyorDie skit became the number one referral to Obama's Healthcare.gov website.
