Ok, he didn't sing THIS time (he has before). It's a mash up of his speeches and it's set to that "Call Me Maybe" song that's been unleashed onto the radios. You know...the one they play on an infinite loop to drive me completely insane? That one.
You're welcome...I think.
Obama isn't the first world leader to break into tune...the Russian bad-ass himself (Putin) sang Blueberry Hill...he's a scary dude right?
