T-Rex: It's nature's way of saying "YOU NEED OXYGEN TO NOT DIE AND AREN'T GETTING ENOUGH, BABE!"

Dromiceiomimus: It's nature's way of saying "Look, now you're vomiting! Does that help make this clear? Are you understanding why climbing this high is a bad idea now? Are you may be feeling like you like to lower your elevation by 2500 meters or so? BECAUSE YOU DEFINITELY SHOULD."

T-Rex: ...since the historical record shows there was a high peak in China known as 'Big Headache Mountain' as far back as 30 BCE, so WHY are you still doing this??"
