The FX series “Louie” might be one of the dirtiest shows on TV, though fellow FX comedy “It’s Always Sunny in Philadelphia” may give it a run for its money.

Louis C.K. will play himself as a guest on “Red Eye,” and Gutfeld has him on because he is “the only person they could find” that would be willing to come on and defend the practice of self-pleasuring.
