Cartman: Hello, ma'am. I'm working to clean up the neighborhood from parasites. Do you mind if I take a quick look around your house? I'm afraid you may have hippies.
Elderly Woman: Hippies?
Cartman: [walks in and begins to rap the walls with his fist] Yeah, they've been poppin' up all over the neighborhood lately. Ms. Nelson next door had seven hippies in her basement; they usually live in colonies. [raps on the wall and the pitch changes] Hm, I don't like the sound of that. Could I take a look in your attic?
