High Quality Content by WIKIPEDIA articles! "Brian Stewie" is the seventeenth episode of the eighth season, and 150th overall episode, of the animated comedy series Family Guy. It aired on Fox in the United States on May 2, 2010. The episode features anthropomorphic dog Brian and baby Stewie after they are accidentally trapped inside of a bank vault over a long weekend. The two are ultimately forced to reveal their true feelings about each other, and eventually go on to question each other`s existence and purpose in life. Brian and Stewie become even closer to each other as time goes on, and climactically help each other survive being trapped inside the cold, dark vault. The episode breaks from the show`s usual set-up, and is the only episode of the series not to use any cutaway gags.
