Night of the Sentinels: Part 1 - S1-E1
Morph: [imitating Senator Kelly] My fellow Americans, I am an idiot.
Carlos: You know who you are, Gaby? You're the kind of person who would have turned away Mary and Joseph from the inn.
Gabrielle: Well, they should have called ahead.
Shaggy: Scooby-Snacks won't work on me this time.
Daphne: Would you do it for a Shaggy-Snack? A little something I whipped up.
Shaggy: Huh? A Shaggy-Snack?
Daphne: Yes, it's a pot-pie, with pizza crust, anchovies, pepperoni, cherries, all in a thick chocolate sauce.
Shaggy: Hahahaha! I'll do it! I'll do it!
Cartman Gets an Anal Probe - S1-E2
Cartman: How come everything today has involved things either coming in or going out of my ass?
Mike: Where's Vyvyan?
Rik: Well, he said he was going inside to water his plant. Strange that such a ruthless and sadistic maniac as Vyvyan should care for a begonia. Must have had it two years now.
Mike: And it was dead when he got it.
Rik: Yes... Still, give him his credit - he's watered it every day!
Mike: Only because he can't be bothered to go upstairs to the lavatory.
Kimball Cho: What do you need?
Patrick Jane: Backup.
Kimball Cho: I don't like it when you say you need backup and nothing's happened yet.
Courage: There's something fishy goin' on here, or my name is Stinky Looloo, and thank goodness it's not.
Norma Louise Bates: Why do crazy people keep gravitating towards me?
