As “The Late Show” host explained on Tuesday’s show, the timing of the reunion marks the 20th anniversary of Colbert joining Comedy Central’s “The Daily Show”.

“The Daily Show” not only helped make Colbert and Stewart household names, but it also furthered the careers of correspondents like Oliver and Bee. These days, Oliver hosts the Emmy Award-winning “Last Week Tonight” while Bee hosts the always entertaining “Full Frontal”.
