At one point, Stephen Colbert was a correspondent for Good Morning America.  It was 1997.  At the time, Colbert had achieved moderate attention for two things.  He was one of the cast members of the short lived Dana Carvey Show and he provided the voice of Ace on the Saturday Night Live animated sketch, The Ambiguously Gay Duo.

He took a job with Good Morning America.  But, it didn't work out.  Only one segment ever aired.  It is below.

The good part of his short stint at Good Morning America is that it helped lead him to a producer of The Daily Show.
