Most underrated scene in the whole movie.....
"Who are these guys?"
"Most of them are derelicts. They sold their bodies to medicine for money. About 20 dollars, I think?"
"25."
"Righteous bucks!"
"This gentleman here is named Arthur. Arthur was good enough to die last week of heart failure. We are fortunate today to view his body in its pristine state. Here an incision has been made. The ribs have been sawed off, allowing us to remove the breastplate and really observe the human organs as they exist in their natural state. Here we have the human lungs. And here is the human heart
which, you can see (hoists it), is actually located in the center of your chest."
"Ohh! Gnarly!!"
