This video, unearthed by Splitsider, features a young Steve Carell and an even younger Stephen Colbert performing together back in 1993 at Chicago's famed Second City comedy club. (They're joined by fellow funnymen Paul Dinello and David Razowsky, but obviously those guys are a lot less famous.)
This clip, which features the performers singing a little ditty called "The Obvious Song," was part of a show called Take Me Out to the Balkans. Man, look at Steve 'n Stephen -- they're just babies here. Kids really do grow up so fast, don't they?
