With Dane Cook set to guest star on Louie tonight, Vulture thought it would be a good idea to give a bit of a primer on the troubled relationship between Louis CK and Cook. It is! Essentially, it boils down to this: Cook has been accused of stealing a few of Louis’ jokes from 2001’s Live in Houston for his 2005 album Retaliation. Cook has denied it, most notably on his infamous WTF Episode, and Louis doesn’t seem to be holding much of a grudge about it these days. So tonight’s episode should be interesting, to say the least.
