[An elderly woman's home. Cartman rings her doorbell, and she answers it. Cartman is dressed in an orange hazmat suit and is carrying a tank of something on his back]
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?
[The attic. He opens the door and looks in. He gets out a flashlight, turns it on, and looks around again. He stops after a few seconds.]
Cartman: Oh yeah, boy. Take a look at this, ma'am. [she climbs up until her eyes are level with his] See that? Hippies. [five hippies are sitting in a clearing in the attic, smoking and laughing.]
Elderly Woman: Oh my.
Cartman: These are what we call the uh giggling stoners. Pretty common form of hippie, usually found in the attics. Problem is, if you see one hippie, there's probably a whole lot more you're not seein'. Uh, whe-where's the backyard.
[The backyard. The elderly lady opens the door and Cartman walks out onto the back porch]
Cartman: Yep, that's what I thought. See that? You've got a drum circle in your backyard.
