The Godfather - "Luca Brasi sleeps with the fishes."

When the Corleone family can't get a hold of Luca Brasi, they wonder what happened to him and where he is. The answer comes in the form of a mysterious brown paper with Two fish wrapped in a bullet-proof vest inside. As Clemenza explains, "It's a Sicilian message. It means Luca Brasi sleeps with the fishes." In other words, he's been dumped in the ocean for a deep, deep sleep.
