Here's an easy one. Two quotes for your viewing/listening pleasure.

"You know why they put oxygen masks on planes?"
"So they can breathe."
"Oxygen gets you high. In a catastrophic emergency, you're taking giant, panic breaths. Suddenly, you become euphoric. Docile. You accept your fate. It's all right here. Emergeny water landing, six hundred miles an hour. Blank faces, calm as Hindu cows."

"Hey man, what are you reading?"
"Listen to this. It's an article written by an organ in the first person. 'I am Jack's Medulla Oblongata. Without me, Jack could not regulate his heart rate, blood pressure, or breathing.' There's a whole series of these. 'I am Jill's Nipple.' 'I am Jack's colon.'"
"Yeah. I get cancer. I kill Jack."
