Candidate passages:
 "Family Guy" creator Seth MacFarlane created a cartoon short entitled "Life of Larry".
The short centered around a middle-aged man named Larry and his anthropomorphic dog Steve.
In 1999, when MacFarlane was working for Hanna-Barbera Studios, writing for shows such as "Johnny Bravo", "Dexter's Laboratory", and "Cow and Chicken", he made a sequel to "Life of Larry" (the original was broadcast by Cartoon Network in 1995).
The short caught the eye of 20th Century Fox representatives, who asked him to create a TV series revolving around the characters.
MacFarlane received a US$50,000 budget to develop a pilot for the show, which was, as MacFarlane stated in a 2006 interview, " about one twentieth of what most pilots cost".
MacFarlane claims to have drawn inspiration from several sitcoms, namely "The Simpsons" and "All in the Family".
Several premises were also carried over from several 1980s Saturday morning cartoons he watched as a child, namely "The Fonz and the Happy Days Gang", and "Rubik, the Amazing Cube".
In three months, MacFarlane created the Griffin family and developed a pilot for the show he called "Family Guy".
Brian's character was largely based on Steve, and Larry would be the main inspiration for the Peter character. 
When he was still in college, "Family Guy" creator Seth MacFarlane created a cartoon short called "The Life of Larry".
The short centered around a middle-aged man named Larry and his anthropomorphic dog Steve.

Brian's character was largely based on Steve from the "Larry and Steve" cartoon, with Larry serving as the primary basis of the Peter character.

Green was in to the casting of an animated television sitcom called "Family Guy," created by Seth MacFarlane for the Fox Broadcasting Company.
The series centers on the dysfunctional Griffin family and stars MacFarlane, Alex Borstein, Mila Kunis and Mike Henry.
Green primarily voices Chris Griffin, the teenage son, who is overweight, unintelligent and, in many respects, a younger version of his father, and Neil Goldman, a geeky and annoying neighbor.
Green admittedly did an impression of the Buffalo Bill character from the thriller film "The Silence of the Lambs" during his audition.
His main inspiration for Chris' voice came from envisioning how "Buffalo Bill" would sound if he were speaking through a PA system at a McDonald's.
