Its Always Sunny in Philadelphia: Season 4

In the same vein of Seinfeld and Arrested Development It's Always Sunny in Philadelphia focuses on unethical, self-involved characters who not only fail to learn anything resembling morals, but seem to drag down the people around them. Season 4 proves that nothing is sacred at Paddy's Pub in Philadelphia, topping previous seasons with more controversy and ridiculous situations like Dee and Charlie's adventures with cannibalism or when Frank and Charlie try to figure out who pooped in their bed.
