False Synchronicty

A German submarine officer in WW-II looks through the periscope at night for enemy battleships.

The crew of a nearby Allied battleship believes they're in safe waters so the decks are well lit. 

The German officer spots the Allied ship's lights through the periscope, reports to his commander who fires a torpedo. The torpedo makes a direct hit.

Meanwhile, the captain of the Allied battleship, deep in his quarters, muses what terrible luck, we've hit an iceberg. He notes with bitter irony that he was just getting some ice for a shot of whiskey at the very moment his ship struck what he supposed was an iceberg.

For the Allied captain, the ice cubes and the impact of the wrongly imagined iceberg are acausally connected. He radios his base commander and tells the sad story. 

The radio transmission is overheard by the German submarine officers. They laugh uproariously. They know it's no iceberg.
