Not many actors would leave a top-rated network show to work in public service, but Kal Penn did just that in 2009. The actor, whose parents came to the United States from India, gave up his role in Fox's "House" to head to Washington, D.C., where be was named an associate director of the White House Office of Public Liaison. In the position, he works with Asian American youth and arts communities. Kal doesn't hide his flag-waving sentimentality, either. "I'm obviously a patriotic American," he once told The New Republic.
