Stewie Griffin frequently builds dangerous weapons as a baby

If you thought regular toddlers were difficult, imagine one constructing a fully functional time machine out of an old Speak & Spell. Stewie's transition from matricidal mastermind to flamboyant sci-fi adventurer completely ignores the fact that he still wears diapers. The family’s utter obliviousness to his heavily armed arsenal is a beautiful mockery of typical parental negligence in sitcoms.
