Colbert is on Kimmel tonight; Kimmel is on Colbert.

How are they pulling this off? Well, Kimmel is taping in Brooklyn tonight, so no teleporter necessary to get someone from LA to NYC. Beyond that, I guess the two friends are staggering the performances between two different studios a few hours and a few miles apart.

The last time two late night hosts pulled off something this cute is when Kimmel and Fallon, aka, "The Two Jimmys" switched shows for an April Fools performance. I think Fallon few out to Los Angeles while Kimmel flew into New York and they each walked out on each other's stages.
