Agreed; somewhere between Stewie and Brian you've got the perfect role model.
Peter: 'Aw crap. When did they change the meaning of 'for' to 'from'?'
Brian (dryly): 'I think they had a meeting about it last night'
Peter: 'Why wasn't I told?'
Brian (dryly): 'They sent you a card, but it had 'For Peter' written on it so you must have thought it was from you, so you didn't... y'know, it's just easier to call you stupid.'
And I didn't get that reference before, either. Fantastic stuff.
