The man who wouldn't die.

[Marino] gave Malloy unlimited credit, thinking it would soon put an end to him. It didn't; Malloy was in danger of drinking the bar into bankruptcy. Antifreeze, a deadly poison, was substituted for liquor, but still Malloy would drink until he passed out, wake up, and come back for more. Antifreeze was substituted with turpentine, followed by horse liniment, and finally mixed in rat poison. Still Malloy flourished. The gang began to get creative, thinking raw oysters soaked in wood alcohol would do the trick (this idea apparently came from Pasqua, who saw a man die after eating oysters with whiskey, which was probably an anomaly). Then came a sandwich of soiled sardines, carpet tacks, and metal shavings (none of which would likely lead to death in any case).
