Cartman: No, no, Mr. Mackey. We don't have any cigarettes.

And uh, if you start smokin' at an early age, m'kay, it's gonna be bad. M'kay, because, uh, smoking can lead to all kinds of health problems like cancer. M'kay, and let me tell you something about cancer, m'kay. Cancer's bad. M'kay, and, uh, eh, what? What the? [notices fire] Holy shit, m'kay!
