But I think they miss an important aspect. Colbert is mostly funny because of his team- he did quite well, considering it wasn't paid gig.
And I would guess that Laura has better sense of humor than most of the best comedians.
And in terms of the act itself, two is generally funnier than one. A Colbert and Steward could have done a better performance.
