Robin Williams sure picked a doozy of a film to make his comeback with following a serious heart surgery that caused quite a scare for the comedy legend. In 'World's Best Dad,' written and directed by Bobcat Goldthwait, Williams plays the father of a seriously (and we mean seriously) terrible teen, leading to some of the more twisted and darkly hysterical situations we can remember. PopEater had the luxury of chatting with Williams and Goldthwait about the film, which led to many other oft-dirty tangents. Enjoy the interview after the jump:
