Louis CK could care less about which talk show he’s on, just so long as people are watching. Which is why he returned to Leno last night, and had no problems revealing just how much he loved taking Percocet for a back injury — so much so that he indulged Leno with a spit-take — why he’s not an alcoholic or a pot-head (blame Kansas City!), and the rudeness of strangers, and helicopters. Which leads to a clip from the second season of Louie (debuting tonight on FX) and a reminder that Louis CK remains deathly afraid when planes hit turbulence, even if it’s for the cameras.

Brian Regan’s hardcore fans might want to gloss over the first little bit about ranking pain on a scale of 1-10 and just get to the good parts.

Roll it.
