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.
