While he almost certainly won't be lured into a slap fight like Bradley Cooper or get spanked like Justin Bieber (though we can dream, can't we?), President Obama is now the latest celebrity to subject himself to Zach Galifianakis's intensity for an episode of Between Two Ferns. Obama is stopping by in order to encourage young people to sign up for health insurance before the March 31 deadline. The episode will drop at Funny or Die Tuesday at 7:30 a.m., and we're betting it will be good. If anyone can stay dead-pan while humoring sweaty, incoherent people, it's definitely the president.
