I'm a big fan of Seth McFarlane and The Family Guy. The show is like an ADD version of the Simpsons mixed with the Zucker brothers (of Airplane! Fame). For me, Family Guy is the crack of animated comedy.
If you dislike Family Guy, you should probably ignore this post all together (don't even bother commenting about how Family Guy rips off The Simpsons , or how their comedy is mostly gag based instead of character/plot driven like South Park). All I know is that Family Guy makes me laugh, and that's more than most so called comedies (I'm looking at you “According to Jim”).
I recently came across the (poorly recorded) pilot for The Family Guy when it was still called “Life of Larry”. You'll probably notice at least two gags that made it into the Family Guy we all know and love. See for yourself:
