Comedian Louis C.K. appeared on The Tonight Show this week and made some controversial jokes about sex that made host Jimmy Fallon rather uncomfortable.

First, however, the two had a lengthy exchange about C.K.’s love for napping and rocking suits. “That’s my favorite thing to do in the whole wide world. I love napping. I’ll probably take a couple more before I go to bed. I’ll take an 11:30 p.m. nap, and go to bed at midnight. It’s my favorite thing,” C.K. said.

Louis C.K.’s new Netflix special arrives Apr. 4.
