Stephen Colbert Praises Letterman On "The Colbert Report"
(Undated) -- Stephen Colbert knows he'll be following a legend when he takes over the "Late Show" next year. While in character Thursday night, Colbert recalled how David Letterman's stint on late night television began just as he was starting college. Colbert said he learned more from Letterman than he did from his higher education.
