Even though Stewie Griffin him self is only 1 year old I would recommend readers of this book be at least 12 and older for explicit the content written. Ok. In case the sarcasim was a bit misleading this is classic Family Guy. Filthy language and shocking dialog concentrated from the mouth and mind of the youngest quick witted Griffin family member. Stewie will school you with a perspective sharpened from a dozen months of miscalculated matriarcal assassinations.
