The Titanic sank in 1912 after hitting an iceberg in the North Atlantic. The collision is one of history's most documented disasters, with countless investigations determining that the ship struck ice and took on water. The explanation became textbook knowledge: icebergs are hazards to maritime navigation, and the Titanic failed to detect or avoid one. The disaster is attributed to environmental factors and human error in navigation.

Then this fact reframes the entire disaster as Chuck Norris swimming backstroke across the Atlantic while the ship was off course. The implication is that the Titanic, with all its modern (for 1912) navigation technology, couldn't avoid a human being doing recreational exercise. He's not a hazard to shipping; he's an obstacle larger than an iceberg, more dangerous than a full disaster. The ship sank not due to ice but due to human collision.

What's brilliant is the casual framing. He's not attacking the ship or trying to sink it; he's just swimming. The Titanic's collision with him is an accident from his perspective, a minor inconvenience during his recreational activity. The ship's massive size and presumably excellent navigation becomes irrelevant in the face of his presence. An ocean-liner hitting a swimming human is reframed as inevitable consequence of his existence.
