The Simpsons have to win. ^^ They are just epic.
Plus: Familiy Guy copied some jokes/story lines.
Examples?
There is one joke about how the jews don't have to suffer after what they had to suffer in the desert B.C. Simpson made such a joke first, a while afterwars we could see a similar joke in Family Guy.
Another example is: there is an episode in which Marge becomes very strong and Homer doesn't want to sleep with her but she forces him. *g* And there is a similar scene in family guy...
