"Brian Writes a Bestseller" follows anthropomorphic dog Brian after he publishes a self-help book that becomes an immediate success, following the failure of his novel, Faster Than the Speed of Love. Once he hires Stewie as his publicist, however, Brian becomes increasingly self-centered, and fires him when he continues to botch his schedule. However, when Brian goes on Real Time with Bill Maher, he ends up getting a wake-up call from Maher himself.

The ninth season of animated television series Family Guy first aired on the Fox network in eighteen episodes from September 26, 2010, to May 22, 2011, before being released as two DVD box sets and in syndication.
