Steve Carell and Stephen Colbert are funny on their own, but put them together and they're truly sublime. (This should come as a surprise to exactly zero people.) Here's further proof that these two are an incredible comedic powerhouse. In 1993, they were both part of a revue called "Take Me Out to the Balkans" on the stage of Second City.
Check out Carrell and Colbert performing "The Obvious Song," along with castmates Paul Dinello and David Razowsky.
