Dane Cook is a douchebag. There, it's been summarized.
Wikipedia says numerous commentators have characterized Cook as unfunny and banal (whatever the fuck that means, but i'd probably agree if I knew). Comedian Louis C.K. has charged Cook with plagirism, claiming C.K.'s bit "Itchy Asshole" was stolen by Cook. Gee, if i knew plagirisim was such a bad thing, I wouldn't have plagirised this whole article.
