By now you already know that President Obama has nominated Dartmouth College President Jim Yong Kim to head the World Bank. It's a surprise move because Kim is cut from a different cloth than the typical World Bank head.
He's a physician and development expert instead of a banker, career politician or a chief executive.
And, also, he's a rapper.
Here he is performing "Time of My Life" during the finals of last year's "Dartmouth Idol."
