Stephen Colbert greeted the nation with "Happy Earth Day" on his show Thursday night, but don't think that means he's gone green.

"I celebrate Earth Day because it's America's planet," Colbert clarifies.

He goes on to target newspapers such as USA Today and The New York Times for their Earth Day coverage, which involved printing large bonus pullout sections.
