Stephen Colbert dropped in on David Letterman’s late night CBS talk show, the “Late Show” on Tuesday, April 22, to get a glimpse of the rigors of the job he will be doing next year.

Letterman has been the show’s host since its inception. Colbert started out doing bits on “The Daily Show With Jon Stewart” and then developed his own show, “The Colbert Report.”
