Pink Panther: (to Brian after he's been spray painted pink) Welcome to hell.
Justin's mom: I am so sorry, Mrs. Griffin. I have no idea what got in to my son.
Lois: Well, just have him return the candy and everything's fine.
Justin's mom: Justin, you give this young man his candy back right now!
Justin: (gives Stewie his bag of candy back) Alright, here.
Lois: Thanks. Now we want Justin's candy.
Justin's mom: What?
Lois: You heard me. Take Justin's bag of candy and pour it into Stewie's. All of it. And if I think you're holding back on me, we're gonna have a serious problem.
Stewie: Well, alright! That's what I'm talking about! Yeah, a serious problem!
(Justin's mom pours Justin's candy into Stewie's bag)
Lois: Good. Now go in your purse, take out $40 and put it in the bag.
Stewie: Alright, Lois, you're kinda scaring me now.
Justin's mom: I don't have $40!
Lois: Alright, I understand. I'll be back tomorrow for the $80. And I'm taking your welcome mat! (grabs it and walks away)
Stewie saying hello and holding a bazooka at the bullies is a spoof out of "Indiana Jones and the Raiders of the Lost Ark".
