from The Lord of the Rings is shown as the Eye of Sauron in a scene where he is trying to find his lost contact lens. A cutaway scene features Peter in a jail surrounded by inmates who force him to strip, squeeze his boobs together, and sing the chorus from Kelis's 2003 hit “Milkshake.” This is possibly an homage to the scene after the credits in the movie Dodgeball: A True Underdog Story in which Ben Stiller does the same thing in his fatsuit. After Bertram's defeat, the scene cuts away to Stewie and Christopher Moltisanti from The Sopranos digging a hole. The viewer is led to assume that the hole is for Bertram but really it is for a tree Stewie and Christopher are planting. Then Stewie states that Bertram admitted to defeat and ran off after which Christopher calls Bertram a "mook." Reception "Sibling Rivalry" was watched by 7.95 million viewers, making it the 77th most-watched program of the week. In a review of the episode, Bob Sassone of TV Squad noted "If there's one reason I'm glad I watched tonight's episode it's because I learned exactly how a vasectomy is done," adding that "Peter is going to have a vasectomy, so he decides to freeze his sperm before he does it. This leads to a hysterical, yet truly gross, scene where Peter knocks over an entire shelf of sperm samples, and has to refill them, um, himself." Geoffrey D. Roberts of Real Talk Reviews reviewed the episode negatively, writing "many viewers will probably be disappointed with an episode about sibling rivalry between Stewie and newfound half-brother Bertram. Both share the same goal – to rule the Universe. With Bertram nothing more than a whinier version of his half-brother, it turns out one Stewie Griffin is more than enough."
