Peter Griffin isn’t the only one who gets excited when characters say the title of the movie in the movie, the guys over at Videogum do as well and they put together an awesome montage of scenes featuring exactly that. Hopefully they put out another volume soon as there are tons more instances of this happening, the Bond series is notorious for it, for instance.
