23. What phrase did Cartman keep using that finally caused Kyle to lash out at him?
From Quiz "South Park" - "Tonsil Trouble"
Answer:
"I'm not just sure, I'm HIV-positive."
The third time Kyle heard Cartman use the phrase pushed him over the edge:
Kyle: "Will you stop it with that? What part of this is funny to you?"
Cartman: "Kyle, we need to try to find a-"
Kyle: "What part of being infected with a deadly disease do you find funny?"
Cartman: "I don't think it's funny, Kyle."
Kyle: "Then stop saying you're not just sure, you're HIV-positive! This isn't funny, AIDS isn't funny, dying isn't funny, so shut [...] up!"
Cartman: "Well excuse me, Kyle, for trying to keep some optimism, you know? I mean, sometimes when things... seem their darkest you just need to try and stay... HIV-positive. But if you wanna be so HIV-negative all the time, I-"
Kyle: "Knock it off! Right now! This isn't funny! At all!"
Cartman: "Are you sure?"
Kyle: "Yes!"
Cartman: "Are you HIV-positive?"
At that point, Kyle smacked Cartman in the face, putting an end to Cartman's pig-headedness.
