I really like this...

Colbert testifies before Congress - in character. He was there for a real cause...to appeal for better treatment of migrant laborers, but he never broke character.

From the NYTimes:

Stephen Colbert testified in Congress on Friday about an immigration bill that he said — in all truthiness — he had not read, “like most members of Congress.”

And when the comedian was challenged by one disgruntled lawmaker about his expertise, which was based on a single day spent hamming it up in a bean field for his show on Comedy Central, Mr. Colbert, keeping completely in character, said that was enough time to make him an expert on anything.

Mr. Colbert testified before the House immigration subcommittee about the day he recently spent picking vegetables on a farm in upstate New York. The gig was part of the “Take Our Jobs” campaign by the United Farm Workers of America to highlight the work done by migrant workers.

“I certainly hope that my star power can pump this hearing all the way up to C-Span 1,” Mr. Colbert said, before explaining that the “obvious answer is for all of us to stop eating fruits and vegetables — and if you look at the recent obesity statistics you’ll see that many Americans have already started.”

But, he continued, his gastroenterologist had explained to him that fruits and vegetables are an important source of “roughage” and said that he “would like to submit a video of my colonoscopy into The Congressional Record.”

“I don’t want a tomato picked by a Mexican — I want it picked by an American, then sliced by a Guatemalan, and served by a Venezuelan in a spa where a Chilean gives me a Brazilian,” Mr. Colbert said, before turning just perceptibly more serious and talking about how difficult work as a farm worker was.

He did also take the hearing seriously - though still in character - and made a plea to Congress on workers' behalves.
