U.S. President Barack Obama is hamming it up online to promote his health care plan.

Obama joked Tuesday with actor Zach Galifianakis, including poking fun at the poorly reviewed Hangover Part III during an interview on the comedy website Funny or Die.

Galifianakis typically poses awkward questions to celebrity guests appearing on his web series Between Two Ferns, and Obama was no exception.

After being asked how it felt to be "the last black president" and about the false notion that he was born in Kenya, the president pitched sign-ups for health care by the March 31 deadline.

Obama's appearance is part of an effort to reach young Americans crucial to the program's success.

Asked by Galifianakis whether he'd want a third term — which in any case is barred by the U.S. Constitution — Obama said, "If I ran again it would be sort of like doing a third Hangover movie. It didn't really work out very well, did it?"

Galifianakis is one of the stars of the Hangover franchise.
