I know this is off-topic, but many people in these two newsgroup have been really hard on Family Guy. In the show's defense, I want to point out two hilarious gags in the second episode:
A high school cheerleader says, "Isn't it great to be thin and popular?" Another cheerleader cheerfully responds, "Yeah. Let's go throw up."
Family Guy says "All I could afford was that big-ass pinyata." The camera cuts to the big-ass pinyata, which, literally, is haped like a big ass.
Family Guy's biggest flaw, IMHO, is over-derivativeness. And I must agree that the evil baby is not particularly funny. And the characters lack the depth and believability of the characters on The Simpsons, The Critic and Futurama. Nevertheless, occasional hilarious bits like those described above are enough to get me to keep watching.
