All-Star Comics #36

Calvin Stymes invites five lifelong friends and fraternity brothers out to a western ranch, and, as they sit around the campfire, he recounts the legend of the dried-out stream-bed they were camping in. Called Koehaha, or \"Stream of Ruthlessness,\" it runs once every 100 years. Strangely, those who \"drown\" in it don't really die, but neither do they come back to life, for the water washes away a man's better nature and replaces it with a ruthless nature. Each man explains what he might do with a criminal nature, then they all go to bed. Stymes moves onto the river bank while the others drown.
