"Mr. And Mrs. Stewie"
Objectively, this was a pretty decent episode. But maybe I'm just dulled to the charms of Family Guy, but all of this episode's high points reminded me of other, better things.
In this episode, Stewie finally meets his match: a little girl named Penelope (voiced by Cate Blanchett) who is really, truly a homicidal maniac.
This reminded me of: the South Park episode where Cartman wins a game of "Who's More Hardcore?" with Bart Simpson.
Cartman: What's the worst thing you've ever done?
Bart: I stole the head off a statue once.
Cartman: Wow, that's pretty hardcore. Geez. That's like this one time, when I didn't like this kid? So I ground his parents up into chili and fed it to him.
