Ricky Gervais Gives Louis C.K. A Rectal Exam (NSFW VIDEO)

On the third episode of Louis C.K.'s hilarious new FX show, "Louie," we get an extra special treat. Ricky Gervais makes an appearance as Louie's old high school friend-turned-doctor and brings his unique brand of humor along with him. When Louie comes in to see why he's been feeling under the weather, Gervais' character unleashes a world of awkward pain on his old friend. Exclaiming "You don't need a doctor, you need a time machine!" after Louie removes his clothes is just a warm-up for what he really has planned: a full rectal examination.
