Family Guy is renowned for its irreverent humor that rejects traditional storytelling techniques in favor of cutaway gags and detailed movie references. Through the years, the show has grown progressively darker in tone. From Lois trying to seduce her daughter's boyfriend to, well, just about anything that Peter gets up to in each episode, the Griffin family members have all done some terrible things throughout the show's run.

While Family Guy isn't particularly famed for its sentimentality, the show occasionally delights viewers with genuinely moving storylines. At the heart of its sincerity is the enduring friendship between family dog, Brian, and baby Stewie. Although the latter character was originally written as a villainous infant seeking world-domination and matricide, he has softened considerably in later seasons. Here are the sweetest moments between everyone's favorite anthropomorphic canine and precocious baby.

Creator Seth MacFarlane has admitted that his vocal cords take a beating during the making of the show. He must have suffered profoundly, then, when "Brian & Stewie" was made. This bottle episode focuses solely on the titular characters, both voiced by MacFarlane, as they get trapped in a bank vault together.

Without the support of the regular back up players, the episode relies on dialogue between the two characters, and becomes emotional towards the end. When Stewie discovers that Brian has sometimes contemplated taking his own life, the baby is horrified. In a touching moment, Stewie shares his true feelings: ''If I didn't have you I'd be lost... You're the only one I like."

Brian's pseudo-intellectualism has become the butt of the joke in much of the later seasons. In "Brian's Play," he writes a crass play called A Passing Fancy, which proves to be popular. This inspires Stewie to write a play as well and he is eager for Brian to read it. But Brian is devastated when he realizes that the infant's work is far superior to his own. Accordingly, he lies to Stewie that his writing is awful.

When Stewie finds his play buried in the yard, he tells Brian that he's just jealous because his own play was so low-brow that even Peter could easily follow the plot. Stewie is invited to share his work on Broadway, but ends up changing it for the worse, much to the audience's displeasure. In a moving act of friendship, Stewie sabotaged a prime opportunity in order to make his friend happy. The episode received positive reviews, with A.V. Club calling it "surprisingly profound."
