Seth Meyers Does an Iffy Bit on “Late Night” and Jack Black Sings Commentary

If only we knew how many jokes we had to go in so many more sketches.

Seth Meyers had a sketch within a sketch last night as he put forth a typical late night desk piece, but then had Jack Black offer up sing-along commentary on how the bit is really going.

The idea may be a little confusing right now, but it’s pretty great.

Watch it here.
