Dane Cook, Accused of Stealing, to Guest Star on 'Louie' (Watch the Promo!)

For years now, there has been controversy surrounding Dane Cook and Louis C.K., as the two comedians were mired in a feud of sorts over their material. A video circulated online showed that there were striking similarities between the topics chosen by C.K. and Cook, which started rumors that he stole material.

Louis C.K. himself didn't accuse Cook of stealing, but did say that the similarities made him angry for a different reason. "It pissed me off for a very unfair reason, which is I just didn't like the dude," C.K. said. "He bummed me out aesthetically."

But apparently the two exchanged emails and have come to amiable terms with each other. In fact, the water is clear enough between the two that Cook will be appearing as a guest star on Louis C.K.'s show "Louie," which is in part an autobiographical project. In the promo, we see Louie meet with Cook, and Cook is very clearly pissed about something.

Check out the preview for the episode below, and tune in to FX on Thursday for the airing of the full ep.
