With an interesting cast of characters, great political satire, and hilarious Peter Griffin quotes, what's not to love?

Family Guy Is Stewie's Interpretation Of The World

Reddit user iFornication makes an interesting argument for why some people can understand Stewie and why some can't: because the entire show is a manifestation of Stewie's perception of the world, i.e., "How an infant sees the world and tries to understand it from his limited knowledge." The Redditor argues that the shenanigans of the show are extremely exaggerated because it's all from a baby's perspective. His most compelling point is that Brian has the ability to talk, due to the fact that Stewie just understands the dog as a member of the family, all of whom can speak.

Brian's Substance Abuse Issues Are Reflected In The (D)Evolution Of His Character

Uber-confident Reddit user GrandmasterSexay makes a rather compelling argument that over time, Brian's alcoholism has morphed his character, just as the disease does to its victims in real life. He argues that Brian becomes "dumber" over time because he has his "wires crossed," referring to the degenerative effects that alcoholism has on the brain. That said, GrandmasterSexay's categorization of it as "progressive d**chiness" may be a tad harsh.

There Was Another Griffin Child Who Died

Although this deleted Reddit user denigrates his own argument that Peter and Lois had a son who died, it's actually somewhat convincing and the comments help it along. The user points out that Peter explicitly states they had a son who died, and even though it's in a gag, it doesn't change the fact that he said it. 789yugemos points out in the comments that there is even a throwaway gag depicting another child.

Brian Is Intelligent Because He's A Human In A Dog Body

Although Family Guy has been on air roughly since the Carter administration, there are still aspects of the Griffin families life that remain mysterious. For example: Exactly why is Brian Griffin intelligent? 

A writer at WhatCulture theorizes that Brian is smarter than your average dog because he was once a human who had his brain inserted into a canine body by the CIA. Remember, Family Guy is set in the same universe as American Dad! 

In American Dad!, the talking goldfish Klaus is actually a German athlete who had his brain swapped with a fish by the CIA. It's entirely possible, then, that all the intelligent animal characters in Seth McFarlane's shared animated universe are the product of illegal experimentation by the CIA, including Brian Griffin.
