Photos: Kal Penn, Harold & Kumar star, hypes Obama at youth summit

A few years after Harold and Kumar visited White Castle -- but before they escaped from Guantanamo Bay -- Kumar Patel's real-life alter ego, Kal Penn, served a two-year-stint as the associate director of the White House's Office of Public Engagement. In 2008, the House and 24 star campaigned in 26 states for Barack Obama, and Penn followed the President into the big building after that work paid off. Today, he's making the rounds again: Penn stopped by the Organizing For America Colorado Youth Summit to encourage youth to vote (for Obama).
