Erratic good deeds at best, character assassination at worst -- there's nothing remotely PC about this show.
Plenty of slapstick/violence played for humor, but no main characters face life-threatening injury. Dad Peter owns a gun and produces it now and then.
Lots of sexual innuendo and references. Sometimes subtle, sometimes overt.
Pretty frequent use of words like "damn," "hell," "bitch," and "ass," plus lewd references to body parts.
Tons of pop culture references.
Characters drink beer and wine frequently.
