Seth MacFarlane creator of the Family Guy had many incarnations of the humor and characters that eventually led to the Fox TV show. For those familiar with the show its pretty amazing to see the jokes, style and characters develop.
I’m no expert on the history of Family Guy but I’ve seen the Pilot and the earlier shorts involving a character named Larry, his family and talking dog. DevilDucky and their affiliate MilkandCookies has put up a lot of these shorts and its kind of amazing to see how the characters and jokes have evolved.
First there is Seth MacFarlane’s student film “The Life of Larry“:

Next came “Larry and Steve” a short produced for Cartoon Network:

This culminated in the Family Guy pilot which uses a lot of the same jokes and character dynamics:
