The last time Louis CK was on Leno, he replaced a DVD cover of The Tonight Show with his special, Live at the Beacon Theater.

The last time Rory Scovel was on Conan, he dazzled the comedy world with Jon Dore by performing, without breaking, simultaneously a completely different act right next to Dore.

Maybe, something along those lines will happen tonight because Louis CK is returning to The Tonight Show (NBC 11:35PM) and Rory Scovel to Conan (TBS 11PM)
