A television show best described by a shameless plagarism attempt, in an effort to create a cartoon series which could even be 1/2 as entertaining as The Simpsons.
Inspiration, is often the seed for works of great innovation. Imitation, isnt always a bad thing. Influence, is where techniquies are adopted, imitated, learned from and incorporated as a part of one's own unique style. Giving 'nodds', is where a writer will steal an idea for use in one of their own works - yet openly credit the original author. For example, in Office Space, the characters plan to use a bank robbing scheme which was already done in Superman III. So, they introduce this scheme such that one character says "yeah - just like they did in Superman III". Theres no shame in that, its like giving propps.
Then, we have plagarism. Family Guy is a series guilty of shameless idea theft - not just at the dialogue level, or the plot level - but I mean, I have seen exact sequences appear in Family Guy, which were stolen directly from The Simpsons. Its shameless idea theft. It's a crime.
The writers of Family Guy are incapable of creating innovative or original work, so they steal scenes from The Simpsons without even understanding why they are funny.
