According to my father, who served in the Army in WW II, a number of GIs poisoned themselves celebrating VE day with antifreeze. These were young men, not particularly educated.
That ties into the anecdotes of Parisians shouting "Viva Le Prestone!"[1] as troops moved through their city - each Jeep had "Prestone" stenciled on the hood, partially to mark that it'd been treated with antifreeze, and partially to warn GIs against attempting to drink it.
