(Good question...I never thought of it before, may look into obtaining a member crystal).
Some of us might like Family Guy and are familiar with the characters (the Griffin family), the fictional town (Quahog in tiny Rhode Island) and jokes. Critics charge Family Guy is a rip-off of the Simpsons with pinpointed similarities (the Griffins names): a simpleton husband (Peter), a nagging wife (Lois), a troubled son (Chris), a miserable daughter (Meg) and a baby (Stewie, however, a talking mad genius), plus an intellectual dog (Brian) the show brought back from the dead. And very much like South Park, Family Guy is controversial (the creator Seth MacFarlane is an outspoken liberal Democrat and atheist), not PC (plenty of stereotypes in minor characters) and pokes fun of moral and social convictions.
