What makes the grass grow?

A line in the 1985 screen play, Full Metal Jacket, written by Stanley Kubrick.

Gunnery Sergeant Gerheim asks, "What do
we do for a living, ladies!" and the platoon
replies, "KILL! KILL! KILL!"

He then asks, "What makes the grass grow?"
and they reply "BLOOD! BLOOD! BLOOD!"
