Jericho, Season 1

Mimi:
You know, you listen to me, Stanley. Your sister's not a child any more. You can't just throw this fit and kick Sean's ass and think that's going to be the end of it.

Stanley:
Well, I hope you're going to explain to me why I can't.

Mimi:
Because if you do, she's just going to latch on that much tighter; unless they get really angry, in which case the age-old teenage remedy is to run away, which used to mean that you'd hear from them in a few days when they ran out of bus money. Nowadays, chances are much better that you'll find their bodies on the side of a road. Look, right now it is under our roof and it's a pain in the ass, I know. But it's a safe and manageable pain in the ass and I suggest you let him stay here before it turns into more than that.
