Stephen Colbert To Guest Star On The Office

Worlds are colliding once again on The Office. With the addition of Clark Duke to the cast, Dunder Mifflin will be a very mini Hot Tub Time Machine reunion, as Duke joins fellow hot tub time traveler Craig Robinson in the NBC comedy series. And now it seems The Colbert Report's Stephen Colbert will be reuniting with former Daily Show correspondent Ed Helms in the series later this season.
