This episode was one my favorites of the show, and definitely my favorite of the past few seasons. It's about time they actually write an episode that has a story and doesn't deviate from it for some gag that isn't funny, makes no sense, and doesn't advance the plot at all. It reminded me why I even liked this show in the first place, the characters. I really liked this character study type of episode, and while it can't happen every week it was a great change of pace.
I don't see how someone can say there was nothing funny or no joke... Stewie using their only call to talk about a bad movie and a sweater, the whole poop/vomit thing, the bullet ricocheting far longer than scientifically possible, a drunk baby dancing, Stewie trying to entice Brian with creepy yoga poses, the ear piercing... all seemed like jokes to me. They just actually put effort into into telling a story, examining characters, and having them actually interact without some absurdly stupid incident every 2 minutes to distract from it like in every other episode.
