AFI #012 Robert Duvall as Lt. Col. Bill Kilgore from Apocalypse Now (1979)

You smell that? Do you smell that? Napalm, son. Nothing else in the world smells like that. I love the smell of napalm in the morning. You know, one time we had a hill bombed, for twelve hours. When it was all over I walked up. We didn't find one of 'em, not one stinkin' dink body. The smell, you know that gasoline smell, the whole hill. Smelled like … victory. Someday this war's gonna end.
