Louis C.K. on ‘Leno': ‘I Love Percocet’ (Video)

The stand-up comedian, whose FX show returns Thursday, rocked “The Tonight Show”

In the past year, Louis C.K. has gone from being a cultish comedian's comedian to a likely Emmy-nominated TV star thanks to his strong work on FX's "Louie," which returns for its second season Thursday at 10:30 p.m. ET.

On Wednesday, Louis C.K. stopped by "The Tonight Show" to pimp the return of his hilarious sitcom, in which he plays a frequently perplexed divorced father of two girls. He basically did his stand-up routine while chatting with host Jay Leno.

In the three videos below, he admits he's a Percocet addict, disses Kansas City and talks about how a scene from this season of "Louie" that involves riding in a helicopter proves that he's a wuss.
