Chris: Hey little dude, how about some ice cream?
Stewie: Yes I could go for a frozen treat right about now. But no sprinkles. And for every sprinkle I find, I shall kill you.
EDIT: Meg (about Peter being retarded): I can never go to school again!
Stewie: Oh, yes, Meg, yes-yes yes, everything was going swimmingly for you until this. Yes, yes, THIS is the thing that will ruin your reputation, not your years of grotesque appearance, or your awkward social graces, or that way you clear your sinuses, no no no, it's THIS. Do you hear yourself talk? I might kill you tonight That's the funniest one i've seen today
